Formation of heavy hyperons and antihyperons in DIS at COMPASS
The yields of heavy hyperons and antihyperons have been studied in deep inelastic scattering at the COMPASS experiment at CERN. The data were collected during the years 2003-2004 with a 160 GeV polarised $\mu^{+}$ scattered off a polarised $^{6}$LiD target. Signals from $\Sigma^{\pm}$(1385) and $\ba...

description | The yields of heavy hyperons and antihyperons have been studied in deep inelastic scattering at the COMPASS experiment at CERN. The data were collected during the years 2003-2004 with a 160 GeV polarised $\mu^{+}$ scattered off a polarised $^{6}$LiD target. Signals from $\Sigma^{\pm}$(1385) and $\bar{\Sigma^{\pm}}$(1385) decays were reconstructed. The ratios of $\Sigma^{\pm}/\Lambda$, $\bar{\Sigma^{\pm}}/\bar{\Lambda}$ and $\Lambda/\bar{\Lambda}$ were determined. These ratios were used to tune parameters of the LEPTO generator. Dependence of the yields of heavy hyperons production on $Q^{2}$ has been studied. |
