Exclusive and semi-exclusive $\pi^{+}\pi^-$ production in proton-proton collisions at $\sqrt{s} = 7$ TeV
Vardan Khachatryan, A Sirunyan, Martin Flechl, Adrien Caudron et autres
A measurement is presented of the exclusive and semi-exclusive production of charged pion pairs in proton-proton collisions, pp to p(p*) + pi+pi- + p(p*) here the pi+pi- pair is emitted at central rapidities, and the scattered protons stay intact (p) or diffractively …
