We revisit the standard treatment [Xu, Kharzeev, Satz and Wang, Phys. Rev. C 53, 3051 (1996)] of J/ψ suppression due to gluonic bombardment in an equilibrating quark-gluon plasma. Effects arising from gluon fugacity, relative g − ψ flux, and ψ meson formation time are correctly incorporated in the formulation of the gluon number density, velocity-weighted(More)
We explicitly take into account the effect of hydrodynamic expansion profile on the gluonic breakup of J/ψ's produced in an equilibrating parton plasma. Attention is paid to the space-time inhomogeneities as well as Lorentz frames while deriving new expressions for the gluon number density n g , average dissociation rate˜Γ, and ψ survival probability S. A(More)
Programming the reaction chemistry for superseding the formation of Sm2O3 in a competitive process of formation and dissolution, the crystal growth patterns are varied and two different nanostructures of Sm2O3 in 2D confinement regime are designed. Among these, the regular and self-assembled square platelets nanostructures exhibit paramagnetic behavior(More)
In the article by M. G. Mustafa published in Phys. Rev. C 72, 014905 (2005) the author has estimated the total energy loss of a charm quark and quenching of hadron spectra due to the collisional energy loss of energetic partons in an expanding quark-gluon plasma employing Fokker-Planck equation. We wish to point out through this comment that some of(More)
In a recent paper [Eur. Phys. J C 44, 567 (2005)] we developed a very general formulation to take into account explicitly the effects of hydrodynamic flow profile on the gluonic breakup of J/ψ's produced in an equilibrating quark-gluon plasma. Here we apply that formulation to the case when the medium is undergoing cylindrically symmetric transverse(More)
