Nuclear suppression of the $$\phi $$ ϕ meson yields with large $$p_T$$ p T at the RHIC and the LHC

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We calculate $$\phi $$ ϕ meson transverse momentum spectra in $$\mathrm{p}+\mathrm{p}$$ p + p collisions as well as their nuclear suppressions in central $$\mathrm{A}+\mathrm{A}$$ A + A collisions both at the RHIC and the LHC in LO and NLO with the QCD ...

Swimming with Quarks [PDF]

open access: yesJournal of Physics: Conference Series, 2005
These six lectures, given at the XI Mexican School of Particles and Fields held at Xalapa in August 2004, are on the subject of strong coupling QCD. How this colours and shapes the hadron world in terms of (i) the hadron spectrum, (ii) chiral symmetry breaking, (iii) dynamical mass generation and (iv) confinement, are the topics discussed.

Derivation of the Balitsky-Kovchegov Equation for Quark-Quark Scattering [PDF]

open access: yesarXiv
We derived the BK equation for quark-quark scattering, extending the dipole-hadron scattering framework. This derivation reveals that the quark-quark scattering amplitude grows with increasing quark rapidity. Since the momentum dot product is Lorentz invariant, the coupling constant plays a crucial role in accounting for it.

Top Quark Physics -- a Popular Review [PDF]

open access: yesarXiv, 1995
The top quark has been discovered at FERMILAB last year. The following features of top quark physics will be discussed in this article: the top quark in the standard model production and decay of the top quark in proton collisions (direct evidence for top) virtual effects of top quarks in electroweak observables (indirect evidence for top)

Estimation of the Properties of Quarks. II. Scalar Quark?Quark Interaction [PDF]

open access: yesAustralian Journal of Physics, 1970
Describing the hadrons by a relativistic independent quark model, using the Dirac equation with a scalar potential for the effective interaction, the range of the quark-quark interaction is found to lie between O 3 and 0 4 fm. The hadronic spectrum is shown to be independent of the quark mass and the form of the quark-quark interaction.
