Polarization measurement of $I^_{c}^{+}$ and $I^_{c}^{-}$ baryons in $p$ Ne collisions at $s_{N N} = 68.6$ GeV

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1174

The first measurement of the polarization of charm baryons by the LHCb experiment recorded in fixed-target mode is presented. The polarization of $I^_{c}$ baryons is studied in colli…
