We present measurements of second-order azimuthal anisotropy $({v}_{2})$ at midrapidity $(|y|<1.0)$ for light nuclei $d,\phantom{\rule{0.16em}{0ex}}t,\phantom{\rule{0.16em}{0ex}}^{3}\mathrm{He}$ (for $\sqrt{{s}_{NN}}=200$, 62.4, 39, 27, 19.6, 11.5, and 7.7 GeV) and antinuclei $\overline{d}$ ($\sqrt{{s}_{NN}}=200$, 62.4, 39, 27, and 19.6 GeV) and $^{3}\overline{\mathrm{He}}$ ($\sqrt{{s}_{NN}}=200$ GeV) in the STAR …

We report on the measurement of $J/\ensuremath{\psi}$ production in the dielectron channel at midrapidity $(|y|<1)$ in $p+p$ and $d+\mathrm{Au}$ collisions at $\sqrt{{s}_{NN}}=200\phantom{\rule{4pt}{0ex}}\mathrm{GeV}$ from the STAR experiment at the Relativistic Heavy Ion Collider. The transverse momentum ${p}_{T}$ spectra in $p+p$ for ${p}_{T}<4\phantom{\rule{4pt}{0ex}}\mathrm{GeV}/c$ and …

We report a new measurement of the midrapidity inclusive jet longitudinal double-spin asymmetry, A_{LL}, in polarized pp collisions at center-of-mass energy sqrt[s]=200 GeV. The STAR data place stringent constraints on polarized parton distribution functions extracted at next-to-leading order from global analyses of …

We report on a measurement of the $\ensuremath{\Upsilon}(1\mathrm{S}+2\mathrm{S}+3\mathrm{S})\ensuremath{\rightarrow}{e}^{+}{e}^{\ensuremath{-}}$ cross section at midrapidity in $p+p$ collisions at $\sqrt{s}=200\text{ }\text{ }\mathrm{GeV}$. We find the cross section to be $114\ifmmode\pm\else\textpm\fi{}38(\mathrm{stat}+\mathrm{\text{fit}}{)}_{\ensuremath{-}24}^{+23}(\mathrm{syst})\text{ }\text{ }\mathrm{pb}$. Perturbative QCD calculations at next-to-leading order in the color evaporation model are in …

We present STAR measurements of the azimuthal anisotropy parameter ${v}_{2}$ for pions, kaons, protons, $\ensuremath{\Lambda},\overline{\ensuremath{\Lambda}},\ensuremath{\Xi}+\overline{\ensuremath{\Xi}}$, and $\ensuremath{\Omega}+\overline{\ensuremath{\Omega}}$, along with ${v}_{4}$ for pions, kaons, protons, and $\ensuremath{\Lambda}+\overline{\ensuremath{\Lambda}}$ at midrapidity for Au+Au collisions at $\sqrt{{s}_{\mathit{NN}}}=62.4$ and 200 GeV. The ${v}_{2}({p}_{T})$ values for all hadron …

We present the scaling properties of $\ensuremath{\Lambda}$, $\ensuremath{\Xi}$, and $\ensuremath{\Omega}$ in midrapidity $\mathrm{Au}+\mathrm{Au}$ collisions at the Brookhaven National Laboratory Relativistic Heavy Ion Collider at $\sqrt{{s}_{NN}}=200\text{ }\text{ }\mathrm{GeV}$. The yield of multistrange baryons per participant nucleon increases from peripheral to central collisions more …

The study on the effect of nitrogen doses and their time of application on Bajra has revealed that increase in nitrogen dose increased the yield and protein content. Higher protein content was found at early stage than at the maturity of the …
