Flavor ordering of elliptic flows at high transverse momentum [PDF]

, 2002
Based on the quark coalescence model for the parton-to-hadron phase transition in ultra-relativistic heavy ion collisions, we relate the elliptic flow ($v_2$) of high $\pt$ hadrons to that of high $\pt$ quarks.

KINETIC DESCRIPTION OF HADRON–HADRON COLLISIONS [PDF]

International Journal of Modern Physics E, 2008
A transport model based on the mean free path approach to describe pp collisions is proposed. We assume that hadrons can be treated as bags of partons similarly to the MIT bag model. When the energy density in the collision is higher than a critical value, the bags break and partons are liberated. The partons expand and can coalesce to form new hadrons.

Proton electromagnetic generalized polarizabilities

Frontiers in Physics
Electromagnetic polarizabilities are fundamental properties of the proton that characterize its response to an external electromagnetic (EM) field. The generalization of the EM polarizabilities to non-zero four-momentum transfer opens up a powerful path ...

Quark number scaling of hadronic pT spectra and constituent quark degree of freedom in p–Pb collisions at sNN=5.02 TeV

Physics Letters B, 2017
We show that the experimental data of transverse momentum (pT) spectra of identified hadrons released recently by ALICE collaboration for p–Pb collisions at sNN=5.02 TeV exhibit a distinct universal behavior — the quark number scaling.

Is X(3872) a possible candidate of hybrid meson

, 2004
The associate productions of X(3872) and J/\psi in hadron collisions and flavor independence of hadrons in ee^+\to X(3872)+hadrons and the decays X(3872)\to \gamma+hadrons are discussed.

Scalar-Quark Systems and Chimera Hadrons in SU(3)_c Lattice QCD [PDF]

, 2007
Light scalar-quarks \phi (colored scalar particles or idealized diquarks) and their color-singlet hadronic states are studied with quenched SU(3)_c lattice QCD in terms of mass generation in strong interaction without chiral symmetry breaking.

Detector-size upper bounds on dark hadron lifetime from cosmology

Journal of High Energy Physics, 2019
We show that in a confining hidden valley model where the lightest hidden particles are dark hadrons that have mass splittings larger than O 0.1 $$ \mathcal{O}(0.1) $$ GeV, if the lightest dark hadron is either stable or decays into Standard Model (SM ...

High energy QCD: multiplicity dependence of quarkonia production

European Physical Journal C: Particles and Fields, 2021
In this paper we propose an approach which demonstrates the dependence of quarkonia production on the multiplicity of the accompanying hadrons. Our approach is based on the three gluon fusion mechanism, without assuming the multiplicity dependence of the

High-energy hadron-hadron collisions and internal hadron structure [PDF]

Nuclear Physics B, 1975
Abstract As shown by many authors, central particle emission in pp collisions at centre-of-mass energies ≳ 20 GeV can be described in terms of independent cluster production. In ref. [1] this process has been related to the quark-gluon picture of nucleon structure.
