An analysis on single and central diffractive heavy flavour production at hadron colliders

Abstract

In this contribution results from a phenomenological analysis for the diffractive hadroproduction of heavy flavors at high energies are reported. Diffractive production of charm, bottom and top are calculated using the Regge factorization, taking into account recent experimental determination of the diffractive parton density functions in Pomeron by the H1 Collaboration at DESY-HERA. In addition, multiple-Pomeron corrections are considered through the rapidity gap survival probability factor. We give numerical predictions for single diffractive as well as double Pomeron exchange (DPE) cross sections, which agree with the available data for diffractive production of charm and beauty. We make estimates which could be compared to future measurements at the LHC.

Single diffractive production of open heavy flavor mesons

“…Since the structure of the Pomeron is relatively well understood and largely does not depend on the process, the existence of the rapidity gap allows us to separate the strong interactions involving different hadrons. While conventionally diffractive production of mesons has been studied in ep collisions, there are various theoretical suggestions to use pp collisions for studies of the diffractive production of prompt quarkonia [2][3][4][5][6], dijets [7], gauge bosons [8], Higgs bosons [9], heavy quarks [10][11][12], quarkonia pairs [13], and Drell-Yan processes [14]. The possibility of measuring diffractive production in pp collisions has been demonstrated at the Tevatron [15][16][17][18][19], while at the LHC, some diffractive processes (e.g., single diffractive pp → pX) have been measured with very good precision [1], although diffractive production of additional heavy hadrons so far has not been explored in depth (see, however, the preliminary feasibility study [20]).…”
