Calculation of some properties of the vacuum [PDF]

, 2002
In this article, we calculate the dressed quark propagator with the flat bottom potential in the framework of the rain-bow Schwinger-Dyson equation, which is determined by mean field approximation of the global colour model lagrangian.

Covariant and heavy quark symmetric quark models [PDF]

Physical Review D, 1994
There exist relativistic quark models (potential or MIT-bag) which satisfy the heavy quark symmetry (HQS) relations among meson decay constants and form factors. Covariant construction of the momentum eigenstates, developed here, can correct for spurious center-of-mass motion contributions.Proton form factor and M1 transitions in quarkonia are ...

The $$\varvec{\Lambda _b\rightarrow \Lambda (\rightarrow p\pi ^-)\mu ^+\mu ^-}$$ Λ b → Λ ( → p π - ) μ + μ - decay in the aligned two-Higgs-doublet model

European Physical Journal C: Particles and Fields, 2017
The rare baryonic decay $$\Lambda _b\rightarrow \Lambda (\rightarrow p\pi ^-)\mu ^+\mu ^-$$ Λ b → Λ ( → p π - ) μ + μ - provides valuable complementary information compared to the corresponding mesonic $$b\rightarrow s\mu ^+\mu ^-$$ b → s μ + μ ...

Charm quarks are more hydrodynamic than light quarks in final-state elliptic flow [PDF]

Phys. Rev. C 99, 044911 (2019), 2018
We study the charm quark elliptic flow ($v_{2}$) in heavy ion as well as small system collisions by tracking the evolution history of quarks of different flavors within a multi-phase transport model. The charm quark $v_{2}$ is studied as a function of the number of collisions the charm quark suffers with other quarks and then compared to the $v_{2}$ of

Freeze-in Dirac neutrinogenesis: thermal leptonic CP asymmetry

European Physical Journal C: Particles and Fields, 2020
We present a freeze-in realization of the Dirac neutrinogenesis in which the decaying particle that generates the lepton-number asymmetry is in thermal equilibrium.
