Cross section measurements of new baryonic state at 1522 decaying to K0s(anti)protons
Plots for preliminary:
Fig.1: fits for different Q2 ranges
Fig.2: cross sections
Fig.3: ratio theta+/Lambda
Cross section for preliminary (PT>0.5, |eta|<1.5, Q2>20 GeV2, 0.04 < y<0.95):
sigma(ep->e Theta+ X -> e K0 p X)= 125 +/- 27 (stat.) + 36 - 28 (syst) pb
Ratio Theta+/Lambda for preliminary (PT>0.5, |eta|<1.5, Q2>20 GeV2, 0.04 < y<0.95):
sigma(ep->e Theta+ X -> e K0 p X) / sigma(ep->e Lambda X)= 4.2 +/- 0.9 (stat.) + 1.2 - 0.9 (syst) %
