Modeling pion and proton total cross-sections at LHC

Understand

To settle the question whether the growth with energy is universal for different hadronic total cross-sections, we present results from theoretical models for pion-proton, proton-proton and proton-antiproton total cross-sections.

• We show that present and planned experiments at LHC can differentiate between different models, all of which are consistent with presently available (lower energy) data.
• This study is also relevant for the analysis of those very high energy cosmic ray data which require reliable pion-proton total cross-sections as seeds.
• A preliminary study of the total pion-pion cross-sections is also made.
