Multiparton interactions and production of minijets in high energy hadronic collisions

Autor: R. Ragazzon, D. Treleani

Publikováno v: Physical Review D. 53:55-62

We discuss the inclusive cross section to produce two minijets with a large separation in rapidity in high energy hadronic collisions. The contribution to the inclusive cross section from the exchange of a BFKL Pomeron is compared with the contributi

Publikováno v: Journal of Physics A: Mathematical and General. 27:2161-2166

The modifications of the electromagnetic coupling in the presence of a strong external magnetic field are further investigated. The case of non-vanishing momentum transfers acid the induced anisotropy of space are explicitly taken into account. We co

Rapidity gaps and production of minijets in high-energy hadronic collisions

Autor: G. Calucci, D. Treleani, R. Ragazzon

High energy hadronic interactions can produce a final state characterized by minijets separated by a large gap in the rapidity distribution of the produced secondary particles. We discuss the process by keeping into account the possibility of having
