Reanalysis of the top-quark pair production via the e+e− annihilation near the threshold region up to N3LO QCD corrections Phys. Lett. B (IF 4.4) Pub Date : 2024-04-22 Jiang Yan, Xing-Gang Wu, Zhi-Fei Wu, Jing-Hao Shan, Hua Zhou
In this paper, we present an improved analysis of the top-quark pair production via the process near the threshold region up to next-to-next-to-next-to-leading order (NLO) QCD corrections. Near the threshold region, the top-quark velocity tends to zero, leading to Coulomb singularity. To achieve a reasonable prediction in the threshold region, we reconstruct the analytical expression for the Coulomb-terms

Correlation of the hyperon potential stiffness with hyperon constituents in neutron stars and heavy-ion collisions Phys. Lett. B (IF 4.4) Pub Date : 2024-04-21 Si-Na Wei, Zhao-Qing Feng, Wei-Zhou Jiang
The breaking of SU(6) symmetry to a more general flavor SU(3) symmetry could serve as a potential explanation for the “hyperon puzzle” of neutron stars by adjusting the hyperon potentials. Specifically, when the soft relativistic mean-field (RMF) Λ hyperon potentials fall within the domains of chiral SU(3) interactions NLO13 with two-body forces, the maximum mass of neutron stars is expected to be

Two-point closed string amplitudes in the BRST formalism Phys. Lett. B (IF 4.4) Pub Date : 2024-04-18 Isao Kishimoto, Shigenori Seki, Tomohiko Takahashi
Two-point tree-level amplitudes in bosonic closed string theory are described by a correlation function within the BRST formalism, which respects manifest Lorentz and conformal invariance. In the derivation of the two-point amplitudes, we use the mostly BRST exact operator, which has been introduced for two-point open string amplitudes, and a closed string vertex with ghost number three, which has

The dominant production of isomers compared to the corresponding ground states was consistently revealed in the -decay spectra. Deduced IR of Po

Ideal gas thermodynamics with an invariant energy scale Phys. Lett. B (IF 4.4) Pub Date : 2024-04-18 Sudipta Das
A viable approach towards Quantum Gravity is the Doubly Special Relativity (DSR) framework in which an observer-independent finite energy upper bound (or a finite smallest length scale) appears quite naturally. In this work, we have studied the thermodynamic properties of an ideal gas in a specific DSR framework, known as the Magueijo-Smolin (MS) Model. We use the fact that DSR can be considered as

Gravitationally modulated quantum correlations: Discriminating classical and quantum models of ultra-compact objects with Bell nonlocality Phys. Lett. B (IF 4.4) Pub Date : 2024-04-18 Luciano Petruzziello, Fabrizio Illuminati
We investigate the relation between quantum nonlocality and gravity at the astrophysical scale, both in the classical and quantum regimes. Considering a gedanken experiment involving particle pairs orbiting in the strong gravitational field of ultra-compact objects, we find that the violation of Bell inequality acquires an angular modulation factor that strongly depends on the nature of the gravitational

Reissner-Nordström black holes surrounded by perfect fluid dark matter: Testing the viability of weak gravity conjecture and weak cosmic censorship conjecture simultaneously Phys. Lett. B (IF 4.4) Pub Date : 2024-04-18 Jafar Sadeghi, Saeed Noori Gashti
A possible violation of the weak gravity conjecture (WGC) by cosmic censorship is one of the major challenges in the field of general relativity. The cosmic censorship is a fundamental principle that ensures the consistency of the theory of gravity. According to this principle, a charged black hole in four dimensions cannot violate the weak cosmic censorship conjecture (WCCC) under normal conditions

Castellano, Ruiz, and Valenzuela recently observed a remarkable “pattern” in infinite-distance limits of moduli spaces in quantum gravity, which relates the field space variation of the mass of the lightest tower of particles to the field space variation of the species scale. In this work, we show how a version of this pattern can be proven to hold for BPS particles and strings throughout the vector

Small neutrino masses confirmed in the neutrino oscillation experiments indicate the need for new physics beyond the standard model. Seesaw mechanism is an interesting way to extend the standard model for explaining the neutrino masses. In a low-scale type-I seesaw mechanism, the tiny masses of neutrinos can be explained by heavy Majorana neutrino masses. Heavy Majorana neutrinos can lead to lepton-number-violating

The ultimate dream of unification models consists in combining both gauge and Yukawa couplings into one unified coupling. This is achieved by using a supersymmetric exceptional gauge symmetry together with asymptotic unification in compact five-dimensional space-time. The ultraviolet fixed point requires fermion generations: one in the bulk, and the two light ones localised on the boundary in order

In light of the recently discovered -boson mass anomaly by the CDF Collaboration, we discuss two distinct mechanisms that could possibly explain this anomaly through the introduction of high-dimensional scalar multiplets.

Lepton flavor violation by two units Phys. Lett. B (IF 4.4) Pub Date : 2024-04-02 Julian Heeck, Mikheil Sokhashvili
Charged lepton flavor violation arises in the Standard Model Effective Field Theory at mass dimension six. The operators that induce neutrinoless muon and tauon decays are among the best constrained and are sensitive to new-physics scales up to GeV.

We show that the doubly charged scalar from the -triplet Higgs field in the Left-Right Symmetric Model has its mass governed by a hidden symmetry so that its value can be much lower than the breaking scale.

On some quantum correction to the Coulomb potential in generalized uncertainty principle approach Phys. Lett. B (IF 4.4) Pub Date : 2024-03-26 M. Baradaran, L.M. Nieto, S. Zarrinkamar
Taking into account the importance of the unified theory of quantum mechanics and gravity, and the existence of a minimal length of the order of the Planck scale, we consider a modified Schrödinger equation resulting from a generalized uncertainty principle, which finds applications from the realm of quantum information to large-scale physics, with a quantum mechanically corrected gravitational interaction

High-resolution momentum distributions from low-resolution wave functions Phys. Lett. B (IF 4.4) Pub Date : 2024-03-25 A.J. Tropiano, S.K. Bogner, R.J. Furnstahl, M.A. Hisham, A. Lovato, R.B. Wiringa
Nucleon momentum distributions calculated with a common one-body operator vary with the resolution scale (and scheme) of the Hamiltonian used. For high-resolution potentials such as Argonne (AV18) there is a high-momentum tail, reflecting short-range correlations in the nuclear wave function, which is reduced or absent for softer, lower-resolution interactions. We explore if the similarity renormalization

Modular invariant holomorphic observables Phys. Lett. B (IF 4.4) Pub Date : 2024-03-24 Mu-Chun Chen, Xueqi Li, Xiang-Gan Liu, Omar Medina, Michael Ratz
In modular invariant models of flavor, observables must be modular invariant. The observables discussed so far in the literature are functions of the modulus and its conjugate, . We point out that certain combinations of observables depend only on , i.e. are meromorphic, and in some cases even holomorphic functions of . These functions, which we dub “invariants” in this Letter, are highly constrained

NICA prospects in searches for light exotics from hidden sectors: The cases of hidden photons and axion-like particles Phys. Lett. B (IF 4.4) Pub Date : 2024-03-24 Dmitry Gorbunov, Dmitry Kalashnikov
We present first estimates of NICA sensitivity to Standard Model extensions with light hypothetical particles singlet under the known gauge transformations. Our analysis reveals that NICA can explore new regions in the parameter spaces of models with a hidden vector and models with an axion-like particle of masses about 30-500 MeV. Some of these regions seem unreachable by other ongoing and approved

The non-spherical ground state of Proca stars Phys. Lett. B (IF 4.4) Pub Date : 2024-03-24 C.A.R. Herdeiro, E. Radu, N. Sanchis-Gual, N.M. Santos, E. dos Santos Costa Filho
Spherical Proca Stars (PSs) are regarded as the ground state amongst the family of PSs. In accordance, spherical PSs are thought to have a fundamental branch of stable solutions. In this , we provide energetic, morphological and dynamical evidence that spherical PSs are actually excited states. The ground state is shown to be a family of static, non-spherical, in fact , PSs. The spherical stars in
