Experiment WA91 searches for non-q (q) over bar mesons produced in the central region in the reaction pp --> p(f)(X(0))p(s) at 450 GeV/c using the CERN Omega Spectrometer. WA91 is a continuation of the WA76 experiment which has studied this reaction using beams of 85 and 300 GeV/c. Preliminary results from experiment WA91 are presented. In particular the X(1450) and X(1900) observed for the first time in the pi(+)pi(-)pi(+)pi(-) channel of the WA76 experiment at 300 GeV/c are confirmed by the WA91 data.

Abstract
Experiment WA91 searches for non-q (q) over bar mesons produced in the central region in the reaction pp --> p(f)(X(0))p(s) at 450 GeV/c using the CERN Omega Spectrometer. WA91 is a continuation of the WA76 experiment which has studied this reaction using beams of 85 and 300 GeV/c. Preliminary results from experiment WA91 are presented. In particular the X(1450) and X(1900) observed for the first time in the pi(+)pi(-)pi(+)pi(-) channel of the WA76 experiment at 300 GeV/c are confirmed by the WA91 data.File in questo prodotto:
