TL;DR
This study investigates the potential production of the theta+(1540) baryon in the reaction K+ p -> K+ n pi+ at 11 GeV/c, setting limits on its existence using data from the LASS spectrometer at SLAC.
Contribution
First experimental search for theta+(1540) in the specified reaction at high energy, providing constraints on its production.
Findings
No evidence found for theta+ production.
Set upper limits on theta+ production cross-section.
Contributed to understanding of pentaquark existence constraints.
Abstract
We have studied the reaction K+ p -> K+ n pi+ using an 11 GeV/c K+ beam and the Large Acceptance Superconducting Solenoid (LASS) multiparticle spectrometer facility at SLAC. We put limits on the production of narrow theta+ baryons in this reaction.
