Quark scattering off quarks and hadrons [PDF]
Nuclear Physics A, 2014 The in-medium elastic scattering $qq\to qq, q\bar{q}\to q\bar{q}$ and $\bar{q}\bar{q}\to \bar{q}\bar{q}$ is calculated within the two-flavor Polyakov-loop-extended Nambu-Jona-Lasinio model. The integral and differential quark-quark scattering, its energy and temperature dependence are considered and their flavor dependence is emphasized. The comparison

Probing new physics in class-I B-meson decays into heavy-light final states
Journal of High Energy Physics, 2021 With updated experimental data and improved theoretical calculations, several significant deviations are being observed between the Standard Model predictions and the experimental measurements of the branching ratios of B ¯ s 0 → D s ∗ + L ...

Search for medium response to jet quenching via hadron chemistry around the quenched jets [PDF]
EPJ Web of ConferencesWe present a unique signal of medium response to jet quenching: the enhancement of baryon-to-meson ratios for associated particles at intermediate transverse momentum around the triggered quenched jets.

Jet tomography in high-energy nuclear collisions [PDF]
EPJ Web of Conferences, 2019 When an energetic parton traversing the QCD medium, it may suffer multiple scatterings and lose energy. This jet quenching phenomenon may lead to the suppression of leading hadron productions as well as medium modifications of full jet observables in ...

Quark motional effects on the interquark potential in baryons [PDF]
, 2008 We study the heavy-heavy-light quark ($QQq$) system in a non-relativistic potential model, and investigate the quark motional effect on the inter-two-quark potential in baryons.

Top quark decays into heavy quark mesons [PDF]
Physical Review D, 1996 For top quark decays into heavy quark mesons $ $ and $\bar{B}_c^*$ , a complete calculation to the leading order both in QCD coupling constant $ _s$ and in $v$, the typical velocity of the heavy quarks inside the mesons, is performed. Relatons between the top quark mass and the decay branching ratios are studied.

The Quark Spin Distributions of the Nucleon
, 1998 The quark helicity measured in polarized deep inelastic scattering is different from the quark spin in the rest frame of the nucleon. We point out that the quark spin distributions $\Delta q_{RF}(x)$ are connected with the quark helicity distributions ...
