Parity-violating asymmetry of $W$ bosons produced in $p$ - $p$ collisions

Xun Chen, Yajun Mao, Bo-Qiang Ma

The parity-violating asymmetry is an ideal tool to study the quark helicity distribution in the proton. We study the parity-violating asymmetry of $W^{\pm}$ bosons produced by long…

Decay Probability Ratio of Pentaquark Theta^+ State

Xun Chen, Yajun Mao, Bo-Qiang Ma

The pentaquark state of $Θ^{+} (uu dd s ˉ)$ has been observed to decay with two decay modes: $Θ^{+} \to n K^{+}$ and $Θ^{+} \to p K^{0}$ . The decay probability ratio of the two decay modes…
