A Note on the Connection between Non-Additive Entropy and h-Derivative [PDF]

open access: yesEntropy, 2023
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.

Test of Lepton Universality in b→sℓ^{+}ℓ^{-} Decays. [PDF]

open access: yesPhysical Review Letters, 2022
The first simultaneous test of muon-electron universality using B^{+}→K^{+}ℓ^{+}ℓ^{-} and B^{0}→K^{*0}ℓ^{+}ℓ^{-} decays is performed, in two ranges of the dilepton invariant-mass squared, q^{2}.

Tools for estimating fake/non-prompt lepton backgrounds with the ATLAS detector at the LHC [PDF]

open access: yesJournal of Instrumentation, 2022
Measurements and searches performed with the ATLAS detector at the CERN LHC often involve signatures with one or more prompt leptons. Such analyses are subject to `fake/non-prompt' lepton backgrounds, where either a hadron or a lepton from a hadron decay

Lepton asymmetric universe [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2022
The recent observation of 4He implies that our universe has a large lepton asymmetry. We consider the Affleck-Dine (AD) mechanism for lepton number generation.

A Method to Explore Flavor Symmetries of the 3HDM and Their Implications on Lepton Masses and Mixing

open access: yesSymmetry, 2022
We present a method to identify symmetry groups of the Yukawa sector of the three-Higgs-doublet model and to determine the implication that the symmetry has on the lepton masses and mixing.

Test of Lepton-Flavor Universality in B→K^{*}ℓ^{+}ℓ^{-} Decays at Belle.

open access: yesPhysical Review Letters, 2021
We present a measurement of R_{K^{*}}, the branching fraction ratio B(B→K^{*}μ^{+}μ^{-})/B(B→K^{*}e^{+}e^{-}), for both charged and neutral B mesons. The ratio for the charged case R_{K^{*+}} is the first measurement ever performed.

QLBT: a linear Boltzmann transport model for heavy quarks in a quark-gluon plasma of quasi-particles

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We develop a new heavy quark transport model, QLBT, to simulate the dynamical propagation of heavy quarks inside the quark-gluon plasma (QGP) created in relativistic heavy-ion collisions.

Scotogenic Dirac neutrino mass models embedded with leptoquarks: one pathway to address the flavor anomalies and the neutrino masses together

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
If the leptoquarks proposed to account for the intriguing anomalies observed in the semileptonic B-meson decays, $$R_{D^{(*)}}$$ R D ( ∗ ) and $$R_{K^{(*)}}$$ R K ( ∗ ) , as well as in the anomalous magnetic moment of the muon, $$(g-2)_\mu $$ ( g - 2 ) μ

Thermodynamics and energy loss in D dimensions from holographic QCD model

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We consider the holographic QCD model with a planar horizon in the D dimensions with different consistent metric solutions. We investigate the black hole thermodynamics, phase diagram and equations of state (EoS) in different dimensions.

Thermoelectric properties of the (an-)isotropic QGP in magnetic fields

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
The Seebeck effect and the Nernst effect, which reflect the appearance of electric fields along x-axis and along y-axis ( $$E_{x}$$ E x and $$E_{y}$$ E y ), respectively, induced by the thermal gradient along x-axis, are studied in the QGP at an external
