Heavy Quark Production at a Linear e+e− and Photon Collider and its Sensitivity to the Gluon Content of the Photon

نویسنده

  • P. Jankowski
چکیده

A high energy linear e+e− collider (LC) can also be used as a Photon Collider (PC), using Compton scattering of laser photons on the e+/e− beams. The leading order cross-section for the production of heavy quarks, e+e− → e+e−Q(Q̄)X, at high transverse momenta is calculated for both LC and PC modes. The sensitivity of this process to the parton distribution parametrizations of real photons, especially the gluon content, is tested for both modes.

Heavy Quark Production at the TESLA Collider and its Sensitivity to the Gluon Content in Photon

Heavy quark production is studied at the high energy linear ee collider (LC) TESLA both in its nominal and Photon Collider (PC) mode. Leading order cross-sections are calculated for the production of heavy quarks, ee → ee Q(Q̄)X, at high transverse momenta. The sensitivity of this process to the gluon content in the photon is studied. An ee linear collider with a centre of mass system (CMS) ener...

Photon-Photon and Photon-Hadron Interactions at Relativistic Heavy Ion Colliders

In central collisions at relativistic heavy ion colliders like the Relativistic Heavy Ion Collider RHIC/Brookhaven and the Large Hadron Collider LHC (in its heavy ion mode) at CERN/Geneva, one aims at detecting a new form of hadronic matter — the Quark Gluon Plasma. We discuss here a complementary aspect of these collisions, the very peripheral ones. Due to coherence, there are strong electroma...

High Energy Photon–photon Collisions at a Linear Collider∗

High intensity back-scattered laser beams will allow the efficient conversion of a substantial fraction of the incident lepton energy into high energy photons, thus significantly extending the physics capabilities of an ee linear collider. The annihilation of two photons produces C = + final states in virtually all angular momentum states. An important physics measurement is the measurement of ...

The Unintegrated Gluon Density in the Photon and Heavy Quark Production

The production cross section of heavy quarks in real and virtual photon-photon collisions has been studied. The unintegrated gluon density in the photon was obtained using the CCFM evolution equation for the first time. The gluon density was implemented in the Monte Carlo generator CASCADE, and cross sections for heavy quark production in e + e − collisions were calculated and compared to LEP d...
