Local parity-odd domains are theorized to form inside a quark-gluon plasma which has been produced in high-energy heavy-ion collisions. The local manifest themselves as charge separation along the magnetic field axis via chiral effect. experimental observation of previously reported for collisions at top RHIC energies. In this Letter, we present results beam-energy dependence correlations $\mathrm{Au}+\mathrm{Au}$ midrapidity center-of-mass energies 7.7, 11.5, 19.6, 27, 39, and 62.4 GeV from...

We present the measurement of transverse single-spin asymmetry weak boson production in transversely polarized proton-proton collisions at $\sqrt{s} = 500~\text{GeV}$ by STAR experiment RHIC. The measured observable is sensitive to Sivers function, one momentum dependent parton distribution functions, which predicted have opposite sign from that observed deep inelastic lepton-proton scattering. These data provide first experimental investigation non-universality fundamental our understanding QCD.

We report the first dijet transverse momentum asymmetry measurements from Au+Au and pp collisions at RHIC. The two highest-energy back-to-back jets reconstructed fragments with momenta above 2 GeV/c display a significantly higher imbalance in heavy-ion than reference. When reexamined correlated soft particles included, we observe that these dijets then exhibit unique new feature-momentum balance is restored to observed for jet resolution parameter of R=0.4, while rebalancing not attained...

We present measurements of $B^{+}\rightarrow\rho^{+}\gamma$ and $B^{0}\rightarrow\rho^{0}\gamma$ decays using a combined data sample $772 \times 10^6$ $B\overline{B}$ pairs collected by the Belle experiment $387\times II in $e^{+}e^{-}$ collisions at $\Upsilon (4S)$ resonance. After an optimized selection, simultaneous fit to sets yields $114\pm 12$ $99\pm decays. The measured branching fractions are $(13.1^{+2.0 +1.3}_{-1.9 -1.2})\times 10^{-7}$ $(7.5\pm 1.3^{+1.0}_{-0.8})\times for decays,...

This paper reports detailed observation of coherent production pions in hadron-nucleus interactions at 200 to 400 GeV/c and nucleus-nucleus 2.1 4.5 per nucleon. The analysis is based on a comparative study experimental multiplicity distribution different pseudorapidity bins with Poissonian Chaotic distributions.
