HADRONIC JETS

Contacts: Katarzyna Wichmann (ZEUS), Krzysztof Nowak (H1)

H1 and ZEUS have started to combine their exclusive hadronic jets measurements for a common extraction of the strong coupling α_s and a combined measurement of hadronic jets cross sections. So far no cross sections are combined, but the firtst results of including H1 and ZEUS jet cross section measurements in the QCD analysis of the proton structure and determination of the strong coupling constant are available.

H1 + ZEUS combined results:

• NEW : QCD analysis using jet data with simultaneous determination of strong coupling constant (Preliminary) H1prelim-11-034, ZEUS-prel-11-001
  
  Figures available here

• Precision measurements of α_s at HERA (H1 and ZEUS) (Preliminary) H1 Link , ZEUS Link
  

• H1 selected results

• ZEUS selected results

• Compilation plots of H1 and ZEUS resuts
