Contribution of Neutralino and Chargino to Diagonal Form Factor of Majorana Neutrino in the Minimal Supersymmetric Standard Model

Cumhuriyet Science Journal, 2023
In this study, we have calculated the diagonal form factor and charge radius of Majorana neutrinos in the Minimal Supersymmetry Standard Model (MSSM) using Feynman-'t Hooft gauge and dimensional regularization. From the obtained result of calculations,

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

European 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

European 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

European 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.

Parton splitting scales of reclustered large-radius jets in high-energy nuclear collisions

European Physical Journal C: Particles and Fields, 2022
We carry out the first theoretical investigation on yields and the hardest parton splitting of large-radius jets reclustered from small radius ( $$R=0.2$$ R = 0.2 ) anti- $$k_t$$ k t jets in Pb + Pb collisions, and confront them with the recent ATLAS ...

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

European 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

Jet shape and redistribution of the lost energy from jets in Pb + Pb collisions at the LHC in a multiphase transport model

European Physical Journal C: Particles and Fields, 2022
Jet-medium interaction involves two important effects: jet energy loss and medium response. The search for jet-induced medium excitations is one of the hot topics in jet quenching study in relativistic nuclear collisions.

Large lepton asymmetry from Q-balls [PDF]

, 2002
We propose a scenario which can explain large lepton asymmetry and small baryon asymmetry simultaneously. Large lepton asymmetry is generated through Affleck-Dine (AD) mechanism and almost all the produced lepton numbers are absorbed into Q-balls (L ...

Rare top-quark decays $$t \rightarrow cg(g)$$ t → c g ( g ) in the aligned two-Higgs-doublet model

European Physical Journal C: Particles and Fields, 2022
We update the Standard Model (SM) predictions for the branching ratios of the rare top-quark decays $$t \rightarrow cg(g)$$ t → c g ( g ) , and evaluate the maximum rates that can be reached in the aligned as well as in the four conventional two-Higgs ...

Combined explanations of B-physics anomalies, $$(g-2)_{e, \mu }$$ ( g - 2 ) e , μ and neutrino masses by scalar leptoquarks

European Physical Journal C: Particles and Fields, 2022
We extend the contents of the standard model (SM) by introducing TeV-scale scalar leptoquarks to generate neutrino masses and explain some current observed deviations from the SM predictions, including the anomalous magnetic moments of charged leptons ...
