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).

A Renormalizable Neutrino Mass Model With (Z2 × Z4)⋊Z2(II) 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.

Recently, the Belle II collaboration announced the first measurement of the branching ratio B B + → K + ν ν ¯ $$ \mathcal{B}\left({B}^{+}\to {K}^{+}\nu \overline{\nu}\right) $$ , which is found to be about 2.7σ higher than the Standard Model (SM ...

Potential analysis of holographic Schwinger effect in the magnetized background
We study the holographic Schwinger effect with magnetic field at RHIC and LHC energies by using the AdS/CFT correspondence. We consider both weak and strong magnetic field cases with $$B\ll T^2$$ B≪T2 and $$B\gg T^2$$ B≫T2 solutions respectively. Firstly,

A Note on the Connection between Non-Additive Entropy and h-Derivative
In order to study as a whole a wide part of entropy measures, we introduce a two-parameter non-extensive entropic form with respect to the h-derivative, which generalizes the conventional Newton–Leibniz calculus.

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 are effective at low energies, and a source term, which

Phenomenological anatomy of top-quark FCNCs induced by a light scalar singlet
Scalar singlets under the Standard Model gauge group appear naturally in many well-motivated New Physics scenarios, such as the composite Higgs models. Unlike the Higgs boson in the Standard Model, they can induce large flavour-changing neutral currents (

Baryon electric charge correlation as QCD magnetometer [PDF]
The detection of strong magnetic fields in peripheral heavy-ion collisions is crucial for observing effects such as the chiral magnetic effect but has proven exceptionally difficult.

On Quark–Lepton Mixing and the Leptonic CP Violation
In the absence of a Grand Unified Theory framework, connecting the values of the mixing parameters in the quark-and-lepton sector is a difficult task, unless one introduces ad hoc relations among the matrices that diagonalize such different kinds of fermions.

Lepton flavor violation as a probe of quark-lepton unification [PDF]
The recent measurements of the solar neutrino mixing angle theta_{sol} and the Cabibbo mixing angle theta_C reveal a surprising relation, theta_{sol}+theta_C ~ pi/4. Interpreting this empirical relation as a support of the quark-lepton unification, we find that the PMNS mixing matrix can be decomposed into a CKM-like matrix and maximal mixing matrices,
