The investigation for holographic antiferromagnetism model in Gauss-Bonnet gravity
In this paper, we construct a holographic antiferromagnetism model by introducing two real antisymmetric tensor fields that are coupled to the background gauge field strength and interact with each other within a four-dimensional Gauss-Bonnet gravity background, and investigate the influence of the…

Gauge coupling beta functions and gauge field anomalous dimensions at four loops in the Standard Model
We present the beta functions of the gauge couplings and the anomalous dimensions of the gauge fields in the unbroken phase of the Standard Model at four loops.

Accretion of matter of a new bumblebee black hole
We investigate how the newly obtained static black hole in bumblebee gravity affects the behavior of accreting matter and its observable signatures. The Lorentz–violating parameter that characterizes this geometry modifies photon trajectories and shifts the location of the critical curve that…

BFV quantization and FFBRST of Christ-Lee model
We accomplish the Batalin-Fradkin-Vilkovisky (BFV) quantization of the Christ-Lee model in both polar and Cartesian coordinates. We construct the BRST charge along with gauge-fixing function and obtain the BRST invariant effective action. We also procure the finite field-dependent BRST (FFBRST)…

Scale-invariant bounce cosmology in Weyl f(Q) gravity with quintom signature
We investigate a bouncing cosmological model within the Weyl-type f(Q) gravity framework, employing a power-law form of the non-metricity scalar Q. The model successfully resolves the initial singularity problem by demonstrating a nonsingular bounce, where the universe transitions from a…

Gravitational Lorentz-violating e−+e+→ℓ−+ℓ+ scattering
We investigate the gravitational e−+e+→ℓ−+ℓ+ scattering process within the framework of gravitoelectromagnetism, a weak-field approximation of gravity analogous to Maxwell’s theory of electromagnetism. This process involves the interaction between a fermion and an antifermion mediated by graviton…

Connecting Green’s functions in the Siegel-Zwiebach model through FFBRST transformations
Finite-field-dependent-Becchi-Rouet-Stora-Tyutin (FFBRST) transformations, as proposed by Joglekar and Mandal, generalize the usual BRST ones by allowing the corresponding anti-commuting parameter to be finite and field-dependent and can be used to connect Green functions in different gauges. In…

Derivative portal dark matter
We propose a new kind of Dark Matter: Derivative Portal Dark Matter. This kind of Dark Matter connects to the Standard Model through a massive mediator, which links to the Standard Model in derivative form. The derivative of a mediator in momentum space corresponds to the mediated momentum, which…

Spin effects on motion of charged particles around magnetized black holes in conformally coupled scalar fields
We investigate the dynamics of charged spinning test particles in the spacetime of a magnetized Bocharova-Bronnikov-Melnikov-Bekenstein black hole (BH), an extremal solution of the Einstein-Maxwell-conformally coupled scalar field equations. Using the Mathisson-Papapetrou-Dixon equations, we derive…

Non-extensive and quasi-homogeneous geometrothermodynamics
We study the thermodynamic properties of black holes, taking into account the non-extensive character of their entropy at the thermodynamic and statistical level. To this end, we assume that the Rényi entropy determines the fundamental thermodynamic equation of black holes and is represented by a…

Thermodynamics of P−V criticality in d-dimensional AdS black holes surrounded by a perfect fluid in Rastall theory
We study a d-dimensional Anti-de Sitter (AdS) black hole surrounded by a static anisotropic quintessence field within the framework of Rastall theory. The solution is characterized by several parameters including its mass (M), field structure parameter (Ns), Rastall coupling parameter (ψ), and the…

Explicit construction of states in orbifolds of products of N=2 superconformal ADE minimal models
We generalize the explicit construction of fields in orbifolds of products of N=(2,2) minimal models, developed by A. Belavin, V. Belavin and S. Parkhomenko to include minimal models with D and E-type modular invariants. It is shown that spectral flow twisting by the elements of admissible group…

Analysis of charged compact stars by core-envelope model in f(R, T) gravity
In this manuscript, we explore two static and spherically symmetric, anisotropic, charged stars employing the formalism of modified f(R, T) gravity, where the gravitational Lagrangian is taken as f(R,T)=R+2γT. By introducing a core-envelope structure, we bring a new dimension to stellar modeling in…

Existence of class-I dark energy stellar models
We study the concept of a dark energy star, which is assumed to be composed of both dark and conventional matter in a modified teleparallel gravity. After employing a specific viable stellar model, we build the corresponding equations of motion that govern our further analysis. We then calculate…

On ABCD algebras and associative Yang-Baxter equations
In the present paper we consider the usage of associative Yang-Baxter equations in the theory of classical and quantum ABCD algebras [1]. Classical and quantum associative analogs of the generalized Fredel-Maillet equations for ABCD tensors [2, 3] are found. Two classes of examples — rational and…

Physical features of geometrically deformed anisotropic charged three-dimensional BTZ black holes
This work employs the minimal geometric deformation decoupling scheme to derive interior stellar solutions in the background of an electrically charged BTZ ansatz as a seed metric in three dimensions. In this respect, we impose two different equations of state to determine the deformation function…

Black hole quasinormal modes, greybody factors, sparsity of Hawking radiation and quasi-periodic oscillations in a tetrad-frame Deser–Woodard nonlocal gravity
We investigate a wide range of dynamical and observational signatures of spherically symmetric static black holes in the non-local Deser-Woodard gravity model, distinguished by a non-local parameter α and an integer model order n. Starting from the modified metric functions, we derive the…

Confronting mukhanov parametrization of inflationary equation-of-State with ACT-DR6
We provide a simple yet effective semi-analytical approach to confront Mukhanov Parametrization of inflationary equation-of-state, 1+ω=β(N+1)α, with the latest ACT-DR6 data employing Hamilton-Jacobi formulation. We find that the equation-of-state formalism renders excellent fit to the most recent…

On BRST-related symmetries in the FLPR model with Gribov ambiguities
With the recent revival of interest in the FLPR model, novel features have been reported in the literature. A connection between those new feautures and QCD, involving the Gribov problem, is explored. We investigate the FLPR model in a recently proposed framework of BRST-related symmetries and…

A radiating star in Einstein-Gauss-Bonnet gravity
We generate a radiating star in Einstein-Gauss-Bonnet (EGB) gravity for spacetime dimension N=5 and a shear-free geometry. The temporal boundary condition contains curvature corrections from the Lovelock tensor and reduces to the general relativity limit. A detailed analysis of the model indicates…
