Charged-Lepton Mixing and Lepton Flavor Violation [PDF]
Physics Letters B, 2015 We present a model for calculating charged-lepton mixing matrices. These matrices are an essential ingredient for predicting lepton flavor-violating rates in the lepton number nonuniversal models recently proposed to explain anomalies in B-meson decays ...

Journal of High Energy Physics, 2020 Abstract As is the case for all light coloured Standard Model particles, also photons and charged leptons appear as constituents in ultrarelativistic hadron beams, and admit a parton density function (PDF). It has been shown recently that the photon PDF can be given in terms of the structure functions and form factors for electron ...

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.

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.

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

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 ...

Leptonic and semi-leptonic B decays [PDF]
Nuclear Physics B - Proceedings Supplements, 2001 We present results for the semi-leptonic and leptonic decays of B mesons. These non-perturbative matrix elements are important for constraining the CKM matrix. Results are presented for the pseudoscalar and vector decay constants, as well as flavour breaking ratios and heavy quark symmetry relations.

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.
