$\pi^{-}p$ and $K^{-}p$ elastic scattering at 6.2 GeV/c

Data on 6.2 GeV/c pi /sup -/p and K/sup -/p elastic scattering cross sections are presented in the range 0.3<-t<10.7 (GeV/c)/sup 2/. Large- angle pi /sup -/p scattering differential cross sections oscillate around an average differential cross section of 50 nb/(GeV/c)/sup 2/, with minima at co...

Sumario:Data on 6.2 GeV/c pi /sup -/p and K/sup -/p elastic scattering cross sections are presented in the range 0.3<-t<10.7 (GeV/c)/sup 2/. Large- angle pi /sup -/p scattering differential cross sections oscillate around an average differential cross section of 50 nb/(GeV/c)/sup 2/, with minima at cos theta /sub cm/ approximately=0 and -0.4. The well- known dip at -t=2.8 (GeV/c)/sup 2/ remains constant in t. In the backward direction there is a dip at -u approximately=1 (GeV/c)/sup 2 /. K/sup -/p elastic scattering has a diffraction peak with a slope of 7.30+or-0.08 (GeV/c)/sup -2/ in the region 0.3<-t<0.6 (GeV/c)/sup 2/. The structure at about -t=1 (GeV/c)/sup 2/ is less pronounced than at 5 GeV/c. The large-angle region is characterized by a very fast decrease of the differential cross section with increasing energy. (67 refs).
