With large datasets of $J/\psi$ and $\psi(3686)$ resonances collected at BESIII through electron-positron annihilation, highly precise polarization measurements and studies on the properties of entangled hyperon-antihyperon pairs are available. The BESIII collaboration has recently presented a series of analyses on the transverse polarization measurements in the processes of $J/\psi$ and...

Talk

I present an analysis of the inclusive $H_b \to X_s \gamma$ decay with $H_b$ a beauty baryon, in particular $\Lambda_b$, employing an expansion in the heavy quark mass at ${\cal O}(m_b^{-3})$ at leading order in $\alpha_s$.
For a polarized baryon I show the results for the distribution $\displaystyle\frac{d^2\Gamma}{dy \, d \cos \theta_P}$, with $y=2E_\gamma/m_b$, $E_\gamma$ the...
