Novel signatures for vector-like quarks
(Springer, 2017-06)
We consider supersymmetric extensions of the standard model with a vector-like doublet (T B) of quarks with charge 2/3 and −1/3, respectively. Compared to non-supersymmetric models, there is a variety of new decay modes ...
Heavy-quark symmetries in the light of nonperturbative QCD approaches
(2011-12-01)
We critically review the validity of heavy-quark spin and flavor symmetries in heavy-light decay constants, form factors and effective couplings obtained within a nonperturbative framework, the ingredients of which are all ...

Heavy quark collisional energy loss in the quark-gluon plasma including finite relaxation time
(American Physical Society, 2014-07)
In this paper, we calculate the soft-collisional energy loss of heavy quarks traversing the viscous quarkgluon plasma including the effects of a finite relaxation time τπ on the energy loss. We find that the collisional ...
Identification of the Mass and Stability Interval of Strong Potential in Heavy Mesons

Heavy quark mass effects in parton-to-kaon hadronization probabilities
(Elsevier Science, 2019-03)
We examine the relevance of the heavy quarks masses in the perturbative QCD description of hard interactions where charged kaons are produced in the final state. We extract a set of parton-to-kaon hadronization probabilities ...
Polyakov loop and heavy quark entropy in strong magnetic fields from holographic black hole engineering
(2016-12-22)
We investigate the temperature and magnetic field dependence of the Polyakov loop and heavy quark entropy in a bottom-up Einstein-Maxwell-dilaton (EMD) holographic model for the strongly coupled quark-gluon plasma that ...
