The WA102 Collaboration, D. Barberis et al
TL;DR
This paper investigates the production of baryon-antibaryon systems in proton-proton collisions at 450 GeV/c, providing insights into their production mechanisms and dynamics without discovering new mass structures.
Contribution
It offers a systematic analysis of baryon-antibaryon production in high-energy pp collisions, revealing that these systems are not primarily produced via double Pomeron exchange.
Findings
No significant new mass structures observed
Production systems are not dominated by double Pomeron exchange
Provides detailed production dynamics of baryon-antibaryon systems
Abstract
A study of the centrally produced ppbar, ppbarpi, ppbarpipi and lambda lambda channels has been performed in pp collisions using an incident beam momentum of 450 GeV/c. No significant new structures are observed in the mass spectra, however, important new information on the production dynamics is obtained. A systematic study of the production properties of these systems has been performed and it is found that these systems are not produced dominantly by double Pomeron exchange.
