Strong Effective Coupling, Meson Ground States, and Glueball within Analytic Confinement

open access: yesParticles, 2019
The phenomena of strong running coupling and hadron mass generating have been studied in the framework of a QCD-inspired relativistic model of quark-gluon interaction with infrared-confined propagators.

Mass spectra and radiative transitions of doubly heavy baryons in a relativized quark model [PDF]

open access: yes, 2017
We study the mass spectra and radiative decays of doubly heavy baryons within the diquark picture in a relativized quark model. The mass of the JP=1/2+ Ξcc ground state is predicted to be 3606 MeV, which is consistent with the mass of Ξcc++(3621) newly ...

Probing the composition of sub-millisecond rotating compact stars by r-modes instability [PDF]

open access: yes, 2012
We investigate the implications of the r-modes instability on the composition of a compact star rotating at a sub-millisecond period. In particular, the only viable astrophysical scenario for such an object, wich might present inside the Low Mass X-ray ...

The Quantum Nature of Lorentz Invariance

open access: yesUniverse, 2018
If the reality underlying classical physics is quantum in nature, then it is reasonable to assume that the transformations of fields, currents, energy, and momentum observed macroscopically are the result of averaging of symmetry groups acting in the ...

Flavor physics in the quark sector [PDF]

open access: yes, 2008
In the past decade, one of the major challenges of particle physics has been to gain an in-depth understanding of the role of quark flavor. In this time frame, measurements and the theoretical interpretation of their results have advanced tremendously. A

T-odd quark-gluon-quark correlation function in the light-front quark-diquark model

open access: yesSciPost Physics Proceedings, 2022
We have scrutinized the transverse momentum dependent quark-gluon-quark correlation function. We have utilized the light-front quark-diquark model to study the time-reversal-odd interaction-dependent twist-3 gluon distributions which we have obtained ...

Excited State Mass spectra and Regge trajectories of Bottom Baryons in Hypercentral quark Model [PDF]

open access: yes, 2016
We present the mass spectra of excited states of singly heavy baryons consist of a bottom quark and light quarks (u, d and s). The QCD motivated hypercentral quark model is employed for the three body description of baryons.

Search for top quark decays t → qH with H → γγ using the ATLAS detector [PDF]

open access: yes, 2014
A search is performed for flavour-changing neutral currents in the decay of a top quark to an up-type (c, u) quark and a Higgs boson, where the Higgs boson decays to two photons.

Pion generalized parton distributions within a fully covariant constituent quark model [PDF]

open access: yes, 2016
We extend the investigation of the generalized parton distribution for a charged pion within a fully covariant constituent quark model, in two respects: (1) calculating the tensor distribution and (2) adding the treatment of the evolution, needed for ...

Recent results on top quark mass and properties and rare/anomalous top quarks interactions in CMS

open access: yesSciPost Physics Proceedings, 2022
The amount of data collected by the CMS experiment at the CERN LHC in the second data taking period provides the possibility to study absolute and differential cross sections of top quark interaction processes with high precision.
