Extraction of Effective Parameters From Transverse Momentum Spectra of Heavy Quarkonia in Proton–Proton Collisions at the LHC
The effective string tension κ in the Schwinger mechanism and the effective temperature T in Bose–Einstein statistics are extracted from the transverse momentum pT spectra of heavy quarkonia produced in proton-proton p+p collisions at the Large Hadron Collider (LHC). Here, T derived from the heavy…

Charged Anisotropic Compact Stars in fR,ϕ,X Gravity: A Class I Embedding Approach With Reissner–NordstrÖm Exterior
This work examines the physical characteristics of charged, anisotropic compact spheres within the framework of fR,ϕ,X modified gravity. Starting from a static, spherically symmetric spacetime, we employ an Adler-type ansatz for the temporal metric component gtt. The corresponding radial metric…

Probing the decay A0⟶h0Z∗ in Two-Higgs-Doublet Models in the Inverted Hierarchy Scenario at the Large Hadron Collider
Searches are being carried out at the Large Hadron Collider (LHC) for the decay of the CP-odd scalar (A0) in two-Higgs-doublet models (2HDMs) with natural flavour conservation (NFC) in the channel A0⟶h0Z, where h0 is either the discovered 125 GeV Higgs boson or is an undiscovered CP-even scalar…

Neutrino Magnetic Moment in the Doublet-Singlet Leptoquark Model
The transition magnetic moment for Majorana neutrinos is studied in a simple extension of the Standard Model. This extension incorporates two scalar Leptoquarks S1 and R~2 with quantum numbers 3¯,1,1/3 and 3,2,1/6, respectively. It is found that these Leptoquarks generate a sizable transition…

Approximate Mass Spectra of the Heavy Mesons Under a Coulomb Plus Logarithmic Spin-Dependent Potential Function
In this paper, we presented an approximate analytical treatment of the Coulomb plus logarithmic potential using time-independent perturbation theory to investigate the mass spectra of bottomonium and charmonium mesons for the low-order quantum states. Within the framework of the Schrödinger…

An Overview of Scale Invariance in Proton Structure With Holographic Insights
The concept of self-similarity in the internal structure of the proton, rooted in scale invariance and fractal geometry, provides an intriguing framework for understanding the behavior of parton distribution functions (PDFs), particularly in the small x region probed in deep inelastic scattering…

Scalar Pair Creation in a Cosmic String Spacetime With Coulomb-Type Interactions and a KG-Oscillator–Type Nonminimal Coupling
We present an analytical investigation of the creation of neutral scalar particle–antiparticle pair in the spacetime of a cosmic string under the combined influence of Coulomb-type interactions and a KG-oscillator–type nonminimal coupling. The scalar field is described by a modified Klein–Gordon…

Complementary Probes of the Dimension-6 Operator via Gravitational Waves and Multi-Higgs Production
We investigate the phenomenological consequences of a dimension-6 operator H†H3/Λ2, Λ is the effective scale at which new physics takes over, which modifies the scalar potential of the standard model and can induce a strong first-order electroweak phase transition (SFOEWPT). We estimate the lower…

A Renormalizable Neutrino Mass Model With Z2×Z4⋊Z2II Symmetry
In this work, a renormalizable neutrino mass model based on Z2×Z4⋊Z2 II symmetry is proposed for the modification of the μ−τ reflection symmetry. The hierarchies of lepton masses can be naturally realized, and the lepton mixing is addressed. The predicted intervals of the sum of neutrino mass and…

Deparametrization of General Relativity by Space-Time Filling Unstable D9-Brane With Arbitrary Value of Tachyon
We calculate the algebra of constraints for deparametrized general relativity with a space-time filling unstable D-brane for an arbitrary value of tachyon field T. We also propose observables that have vanishing Poisson brackets with all first-class constraints.

The Purely Leptonic and Semileptonic Decays of Ds∗ Meson
With the potential prospects of the Ds∗ at high-luminosity heavy-flavor experiments in the future, we investigated the CKM-favored and tree-dominated leptonic Ds∗⟶ℓν¯ℓ,ℓ=e,μ,τ and semileptonic Ds∗⟶Mℓ′ν¯ℓ′ M=ϕ,η′,K and ℓ′=e,μ weak decays in the standard model (SM). The theoretical predictions and…

Analytical Description of the Distributions of Primary and Secondary Cosmogenic Particles
In this work, we present an analytical description of the energy distributions of primary and secondary cosmogenic particles on Earth in terms of parameters having clear physical meaning. A modified power law is assumed for energy distributions, incorporating terms such as energy loss/decay, which…

Mass Spectra, Radii, and Decay Widths of Toponium
In this work, the radial Schrodinger equation with a nonrelativistic quark potential model (NRQPM) is solved numerically by employing the shooting method. Calculated numerical wave functions (or solutions) are used to compute the masses, root mean square (RMS) radii, E1, M1 radiative transition…

Temporal Wormholes From Temporal Quantum Correlations
Recent developments in quantum theory suggest a unified treatment of space and time, where spatial and temporal correlations can be regarded as equivalent. Specifically, spatial correlations between two systems at one time have been shown to correspond to temporal correlations of a single system at…

Production of Dileptons in Ultraperipheral Heavy-Ion Collisions With Two-Photon Processes
We study the photoproduction process of dileptons in heavy-ion collision at relativistic heavy-ion collider (RHIC) and large hadron collider (LHC) energies. The equivalent photon approximation, which equates the electromagnetic field of high-energy charged particles to the photon flux, is used to…

T-Symmetry in String Geometry Theory
String geometry theory is one of the candidates of nonperturbative formulation of string theory. In this paper, we have shown that dimensionally reduced string geometry theories have what we call T-symmetry. In the case of the dimensional reduction in space-like directions, the T-symmetry…

Modified 3D Massive Abelian 2-Form Theory With a Single Pseudoscalar Field as a Phantom Field: BRST Approach
We obtain the off-shell nilpotent Becchi–Rouet–Stora–Tyutin (BRST) and anti-BRST symmetry transformations (corresponding to the infinitesimal classical gauge symmetry transformations) for the modified massive three 2+1-dimensional (3D) Abelian two-form gauge theory with a single pseudoscalar field…

Study of Semileptonic B⟶DPℓ+νℓ Decays Based on the SU(3) Flavor Symmetry
Decays B⟶DPℓ+νℓℓ=e,μ,τ with the nonresonance, the charmed vector resonances, the charmed scalar resonances, and the charmed tensor resonances are explored by using the SU(3) flavor symmetry approach. Firstly, the decay amplitudes of different modes are related by the SU(3) flavor symmetry. Then…

Interplay Between MW, ΩCDMh2, and g−2μ in Flavor Symmetry–Based Supersymmetric Models
We study the phenomenological implications of the minimal supersymmetric standard model (MSSM) augmented by a nonabelian flavor symmetry labeled as sMSSM. Incorporating this flavor symmetry allows for a significant reduction in the original plethora of free parameters present in the MSSM…

Heavy Quarkonium States With Baryonic Chemical Potential
In this work, we have studied the dissociation behavior of 1S and 2S states of quarkonium using quasiparticle approach where the Debye mass depends on baryonic chemical potential. The binding energies of the quarkonium states has been obtained by using quasiparticle Debye mass which further depends…
