Abstract For a Lorentzian invariant theory, the entanglement entropy should be a function of the domain of dependence of the subregion under consideration. More precisely, it should be a function of the domain of dependence and the appropriate cut-off. In this paper, we refine the concept of cut-off to make it applicable to timelike regions and assume that the usual entanglement entropy formula also applies to timelike intervals. Using the Rindler method, the timelike entanglement entropy can be regarded as the thermal entropy of the CFT after the Rindler transformation plus a constant $ic\pi/6$ with $c$ the central charge. The gravitational dual of the `covariant' timelike entanglement entropy is finally presented following this method.

The China Dark Matter Experiment (CDEX) is a low background experiment at China Jinping Underground Laboratory (CJPL) designed to directly detect dark matter with a high-purity Germanium (HPGe) detector.In the second phase CDEX-10 with a 10 kg Germanium array detector system, the liquid argon (LAr) anti-compton active shielding and cooling system is proposed.For purpose of studying the properties of LAr detector, a prototype with an active volume of 7 liters of liquid argon was built and operated.The photoelectron yields, as a critically important parameter for the prototype detector, have been measured to be 0.051-0.079p.e./keV for 662 keV Gamma lines at different positions.The good agreement between the experimental and simulation results has provided a quite reasonable understanding and determination of the important parameters such as the Surviving Fraction of the Ar * 2 excimers, the absorption length for 128 nm photons in liquid argon, the reflectivity of Teflon and so on.

Abstract Employing the heavy quark expansion model with the kinetic scheme, we evaluate α S (m c 2 ), the strong coupling constant at the charm quark mass m c with data on inclusive semileptonic decays of charmed mesons. Using the experimental values of semileptonic decay widths of the D 0 and the D + , the value of α S (m c 2 ) is determined to be 0.445±0.009±0.114, where the first uncertainty is experimental and the second systematic. This reported α S (m c 2 ) is in good agreement with the value of α S (m c 2 ) calculated by running α S (m Z 2 ) at the Z 0 boson mass m Z with the renormalization group evolution equation. In addition, values of α S (m c 2 ) obtained individually from each of the D 0 , D + , and D + s mesons are found to be consistent being of the same origin.Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

Abstract In this paper, we delve into the intricate thermodynamic topology of quantum-corrected Anti-de Sitter-&amp;#xD;Reissner-Nordstrm (AdS-RN) black hole within the framework of Kiselev spacetime. By employing the generalized off-shell Helmholtz free energy approach, we meticulously compute the thermodynamic topology of these selected black holes. Furthermore, we establish their topological classifications. Our findings reveal that quantum correction terms influence the topological charges of black holes in Kiselev spacetime, leading to novel insights into topological classifications. Our research findings elucidate that, in contrast to the scenario in which $\omega=-4/3$ with total topological charge $W=0$, in other cases, the total topological charge for the black hole under consideration predominantly stabilizes at +1. This stabilization occurs with the significant influence of the parameters a, c, and $\omega$ on the number of topological charges. Specifically, when $\omega$ assumes the values of $\omega=-1/3$, $\omega=-2/3$ , $\omega=-1$, and 0, the total topological charge consistently be to W = +1.

Abstract Assuming the equilibrium of the QCD system, we have investigated the critical behavior of sixth-, eighth- and tenth-order susceptibilities of net-baryon number, through mapping the results in the three-dimensional Ising model to that of QCD. Both the leading critical contribution as well as sub-leading critical contribution from the Ising model are discussed. When considering only the leading critical contribution, the density plots for susceptibilities of the same order demonstrate a consistent general pattern independent on values of mapping parameters. As the critical point is approached from the crossover side, a negative dip followed by a positive peak is observed in the $\mu_B$ dependence of the three different orders of susceptibilities. When sub-leading critical contribution is taken into account, modifications become apparent in the density plots of the susceptibilities. The emergence of negative dips in the $\mu_B$ dependence of the susceptibilities is not an absolute phenomenon, while the positive peak structure is a more robust feature of the critical point.

Abstract In this paper, we base our analysis on the assumption that the existence of a photon sphere is an intrinsic feature of any ultra-compact gravitational structure with spherical symmetry. Utilizing the concept of a topological photon sphere, we categorize the behaviors of various gravitational models based on the structure of their photon spheres. This innovative approach enables us to define boundaries for black hole parameters, subsequently allowing us to classify the model as either a black hole or a naked singularity. Indeed, we will demonstrate that the presence of this interplay between the gravitational structure and the existence of a photon sphere is a unique advantage that can be utilized from both perspectives. Our observations indicate that a gravitational model typically exhibits the behavior of a horizonless structure (or a naked singularity) when a minimum effective potential (a stable photon sphere) appears within the studied spacetime region. Additionally, in this study, we tried to investigate the effect of this structure on the behavior of the photon sphere by choosing models that are affected by the Perfect Fluid Dark Matter (PFDM). Finally, by analyzing a model with multiple event horizons, we show that the proposed method remains applicable even in such scenarios.

Abstract We investigate the holographic complexity in the backreacted&amp;#xD;gravity backgrounds according to the complexity-action conjecture.&amp;#xD;The backreaction considered here is from the presence of static&amp;#xD;strings evenly distributed over the system. We exploit a probe&amp;#xD;string in the bulk and evaluate the Nambu-Goto action and its&amp;#xD;dependence on backreaction. The results suggest that for slower&amp;#xD;strings the complexity increases with the increasing of&amp;#xD;backreaction, in accordance with the findings of the holographic&amp;#xD;entanglement entropy. While for faster strings, the situation is&amp;#xD;different. Furthermore, we analyze the relation between the&amp;#xD;complexity and the space dimension as well as the string velocity.

Abstract he current study explores the production of charged Higgs particles through photon-photon collisions&amp;#xD;within the context of the Two Higgs Doublet Model, including one-loop-level scattering amplitudes of&amp;#xD;Electroweak and QED radiation. The cross-section has been scanned for plane (mϕ0 , √s) investigating&amp;#xD;the process of γγ → H+H−. Three particular numerical scenarios i.e., low-mH , non-alignment, and short-&amp;#xD;cascade are employed. The decay channels for charged Higgs particles are examined using h0 for low-mH0&amp;#xD;and H0 for non-alignment and short-cascade scenario incorporating the new experimental and theoretical&amp;#xD;constraints along with the analysis for cross-sections. It reveals that at low energy, it is consistently higher&amp;#xD;for all scenarios. However, as √s increases, it reaches a peak value at 1 TeV for all benchmark scenarios.&amp;#xD;The branching ratio of the decay channels indicates that for non-alignment, the mode of decay W ±h0 takes&amp;#xD;control, and for short cascade, the prominent decay mode remains t¯b, while in the low-mH the dominant&amp;#xD;decay channel is of W ±h0. In our research, we employ contemporary machine-learning methodologies&amp;#xD;to investigate the production of high energy Higgs bosons within a 3.0 TeV γγ collider. We have used&amp;#xD;multivariate approaches such as Boosted Decision Trees (BDT), LikelihoodD, and Multilayer Perceptron&amp;#xD;(MLP) to show the observability of heavy-charged Higgs Bosons versus the most significant Standard Model&amp;#xD;backgrounds. The purity of the signal efficiency and background rejection are measured for each cut value.Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

Abstract In this paper, we investigate the nano-Hertz gravitational waves (GWs) emission and the massive primordial black holes (PBHs) formation from the light QCD axion scenario.&amp;#xD;We consider the axion domain walls formation from the level crossing induced by the mass mixing between the light $Z_{\mathcal N}$ QCD axion and axion-like particle.&amp;#xD;A general mixing case is considered that the heavy and light mass eigenvalues do not necessarily have to coincide with the axion masses.&amp;#xD;In order to form the domain walls, the axions should start to oscillate slightly before the level crossing.&amp;#xD;The domain walls must annihilate before dominating the Universe to avoid the cosmological catastrophe.&amp;#xD;Then we focus our attention on the GWs emission from the domain walls annihilation and the PBHs formation from the domain walls collapse.&amp;#xD;We show the predicted GWs spectra with the peak frequency $\sim 0.2\, \rm nHz$ and the peak amplitude $\sim 5\times 10^{-9}$, which can be tested by the future pulsar timing array projects.&amp;#xD;In addition, during the domain walls annihilation, the closed walls could shrink to the Schwarzschild radius and collapse into the PBHs.&amp;#xD;We find that the PBHs in the mass range of $\mathcal{O}(10^5-10^8) M_\odot$ could potentially form in this scenario and account for a small fraction $\sim 10^{-5}$ of the cold dark matter.Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.
