T-violating triple-product correlations in hadronicbdecays

We study T-violating triple-product asymmetries in the quark-level decay $\overrightarrow{b}\mathrm{su}ū$ within the standard model (SM). We find that only two types of triple products are non-negligible. First, the asymmetry in $p_u\cdot (s_u\times s_{ū})$ or $p_{ū}\cdot (s_u\times s_{ū})$ can be as large as about $5\%.$ It can be probed in $\overrightarrow{B}{V}_1{V}_2$ decays, where $V_1$ and $V_2$ are vector mesons. Second, the asymmetry in $s_b\cdot (p_u\times p_s)$ can be in the range 1–3 %. One can search for this signal in decays such as ${\Lambda }_b\to \Lambda {\pi }^{+}{\pi }^{-}.$ All other triple-product asymmetries are expected to be small within the SM. This gives us new methods of searching for new physics.
