Thermodynamics and energy loss in D dimensions from holographic QCD model

open access: yesEuropean 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.

Quark-Meson Coupling Model with Short-Range Quark-Quark Interactions [PDF]

open access: yesProgress of Theoretical Physics, 2001
Short-range quark-quark correlations are introduced into the quark-meson coupling (QMC) model phenomenologically. We study the effect of the correlations on the structure of the nucleon in dense nuclear matter. With the addition of correlations, the saturation curve for symmetric nuclear matter is much improved at high density.

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 ...

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.

Parton splitting scales of reclustered large-radius jets in high-energy nuclear collisions

open access: yesEuropean 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 ...

Runaway quarks [PDF]

open access: yesPhysical Review D, 1995
When heavy nuclei collide, a quark-gluon plasma is formed. The plasma is subject to strong electric field due to the charge of the colliding nuclei. The electric field can influence the behavior of the quark-gluon plasma. In particular, we might observe an increased number of quarks moving in the direction of that field, as we do in the standard ...

Covariant and heavy quark symmetric quark models [PDF]

open access: yesPhysical 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 ...

Several Effects Unexplained by QCD

open access: yesUniverse, 2018
Several new experimental discoveries in high energy proton interactions, yet unexplained by QCD, are discussed in the paper. The increase of the cross sections with increasing energy from ISR to LHC, the correlation between it and the behavior of the ...
