Measurement of the $W \to e ν$ and $Z / γ^{*} \to e^{+} e^{-}$ Production Cross Sections at Mid-rapidity in Proton-Proton Collisions at $s$ = 500 GeV

STAR Collaboration, G. Agakishiev, M. M. Aggarwal +346

We report measurements of the charge-separated $W^{+ (-)} \to e^{+ (-)} + ν_{e} (ν ˉ_{e})$ and $Z / γ^{*} \to e^{+} e^{-}$ production cross sections at mid-rapidity in proton-proton collisions a…

Energy and system-size dependence of two- and four-particle $v_{2}$ measurements in heavy-ion collisions at RHIC and their implications on flow fluctuations and nonflow

The STAR Collaboration, G. Agakishiev, M. M. Aggarwal +344

We present STAR measurements of azimuthal anisotropy by means of the two- and four-particle cumulants $v_{2}$ ( $v_{2} {2}$ and $v_{2} {4}$ ) for Au+Au and Cu+Cu collisions at center of…

Sensitivity of neutron to proton ratio toward the high density behavior of symmetry energy in heavy-ion collisions

S. Kumar, Y. G. Ma, G. Q. Zhang +1

The symmetry energy at sub and supra-saturation densities has a great importance in understanding the exact nature of asymmetric nuclear matter as well as neutron star, but, it is…

Identified hadron compositions in p+p and Au+Au collisions at high transverse momenta at $s_{_{N N}} = 200$ GeV

STAR Collaboration

We report transverse momentum ( $p_{T} \leq 15$ GeV/ $c$ ) spectra of $π^{\pm}$ , $K^{\pm}$ , $p$ , $p ˉ$ , $K_{S}^{0}$ , and $ρ^{0}$ at mid-rapidity in p+p and Au+Au collisions at $\sq…

CUORE crystal validation runs: results on radioactive contamination and extrapolation to CUORE background

F. Alessandria, E. Andreotti, R. Ardito +116

The CUORE Crystal Validation Runs (CCVRs) have been carried out since the end of 2008 at the Gran Sasso National Laboratories, in order to test the performances and the radiopurity…
