F. Abe et al., MEASUREMENT OF (P)OVER-BAR-P SINGLE DIFFRACTION DISSOCIATION AT ROOT-S=546 AND 1800 GEV, Physical review. D. Particles and fields, 50(9), 1994, pp. 5535-5549
We report a measurement of the diffraction dissociation differential c
ross section d(2) sigma(SD)/dM(2)dt for ($) over bar pp --> ($) over b
ar pX at root s = 546 and 1800 GeV, M(2)/s < 0.2 and 0 less than or eq
ual to -t less than or equal to 0.4 GeV2. Our results are compared to
theoretical predictions and to extrapolations from experimental result
s at lower energies.
