System size dependence of intermediate mass fragments in heavy-ion collisions
heavy-ion collisions intermediate mass fragments
2011/7/20
We simulate the central reactions of $^{20}$Ne+$^{20}$Ne, $^{40}$Ar+$^{45}$Sc, $^{58}$Ni+$^{58}$Ni, $^{86}$Kr+$^{93}$Nb, $^{129}$Xe+$^{118}$Sn, $^{86}$Kr+$^{197}$Au and $^{197}$Au+$^{197}$Au at differ...
Jets, Mach cone, hot spots, ridges, harmonic flow, dihadron and $\gamma$-hadron correlation in high-energy heavy-ion collisions
Jets Mach cone hot spots ridges harmonic flow dihadron $\gamma$-hadron correlation high-energy heavy-ion collisions
2011/1/7
Within the AMPT Monte Carlo model, hot spots in the initial transverse parton density are
shown to lead to harmonic flows which all contribute to dihadron azimuthal correlation.
Measurement of W-Boson Polarization in Top-quark Decay in ppbar Collisions at sqrt(s) = 1.96 TeV
W-Boson Polarization Top-quark Decay
2010/3/16
We report measurements of the polarization of W bosons from top-quark decays using 2.7 fb^-1 of ppbar collisions collected by the CDF II detector. Assuming a top-quark mass of 175 GeV/c^2, three measu...
Observation of Events at Very High Q2 in e+p Collisions at HERA
Very High Q2 +p Collisions
2010/4/19
Data collected at the e+p collider HERA at DESY by the experiments H1 and ZEUS have allowed to probe a previously inaccessible domain of very large Q2 in deep-inelastic ep scattering. For Q2 > 15000 G...
