Hard exclusive hadron nucleon scattering and color transparency

Heppelmann, S. ; Wu, J.Y. ; Appel, R. ; et al.
Nucl.Phys.A 527 (1991) 581C-583C, 1991.
Inspire Record 327578 DOI 10.17182/hepdata.36761

We present preliminary results on the measurement of a variety of exclusive hadron interactions at center of mass scattering angles of 90°. Data are also presented which show the relative transparency of nuclei to πp and pp elastic scattering in this kinematic range.

Comparison of Exclusive Reactions at Large $T$

Baller, B.R. ; Blazey, G.C. ; Courant, H. ; et al.
Phys.Rev.Lett. 60 (1988) 1118-1121, 1988.

Cross sections or upper limits are reported for 12 meson-baryon and two baryon-baryon reactions for an incident momentum of 9.9 GeV/c, near 90° c.m.: π±p→pπ±,pp±,π+°±,K+Σ±, (Λ0/Σ0)K0; K±p→pK±; p±p→pp. By studying the flavor dependence of the different reactions, we have been able to isolate the quark-interchange mechanism as dominant over gluon exchange and quark-antiquark annihilation.

Backward rho+ production in pi+ p reactions at 5.2 gev/c

Carlson, P.J. ; Fleury, P. ; Lundby, A. ; et al.
Phys.Lett.B 33 (1970) 502-504, 1970.
Inspire Record 69380 DOI 10.17182/hepdata.28538

Using wire spark chambers we have observed the backward production of ϱ + mesons in the reaction π + p → p (missing mass) at 5.2 GeV/ c . In the four-momentum interval −0.80 < u < −0.006 (GeV/ c ) 2 the angular distribution shows a backward peak. In contrast to backward π + p elastic scattering, there is no dip in the angular distribution at u ≈ −0.15 (GeV/ c ) 2 . The ϱ + decay is found to be compatible with isotropy.
