Direct photon production at HERA, the Tevatron and the LHC
نویسندگان
چکیده
We review several most recent prompt-photon measurements at HERA and the Tevatron and discuss their implication for future measurements at the LHC. A comparison to Monte Carlo models, as well as to NLO QCD predictions based on the standard DGLAP and the kT -factorization approaches is discussed. Effects from renormalization and factorization scale uncertainties, as well as uncertainties on the gluon density distribution inside a proton are discussed.

Jet physics at HERA, Tevatron and LHC
In this short report, we discuss the Jet Physics results and perspectives at HERA, Tevatron and LHC. The different accelerators are complementary as shown in Fig. 1, where the kinematical plane in (x,Q) is displayed (x and Q are respectively the proton momentum fraction carried by the interacting parton and the transferred energy squared carried by the virtual photon). HERA allows to reach very...

In this research, we have investigated the effect of spin orientation of quarks on the production of the Bc(1S) heavy mesons. We have calculated the fragmentation functions at initial scale µ° .Then we have modified to µ these fragmentation functions by using Altrali-Parisi equation. Also, we have calculated the transverse momentum distributions of the differential cross sections . Our results...
متن کاملA review of forward proton tagging at 420m at the LHC, and relevant results from the Tevatron and HERA
We review the theoretical and experimental motivations behind recent proposals to add forward proton tagging detectors to the LHC experiments as a means to search for new physics. We also review the current diffractive programs at the Tevatron and HERA, focusing in particular on measurements which will have a direct impact on the case for forward detectors at the LHC.
متن کاملDouble Diffractive Higgs and Di-photon Production at the Tevatron and LHC
We use the POMWIG Monte Carlo generator to predict the cross-sections for double diffractive higgs and di-photon production at the Tevatron and LHC. We find that the higgs production cross-section is too small to be observable at Tevatron energies, and even at the LHC observation would be difficult. Double diffractive di-photon production, however, should be observable within one year of Tevatr...
متن کاملDiffraction at HERA, the Tevatron and the LHC
In these lectures, we present and discuss the most recent results on inclusive diffraction from the HERA and Tevatron colliders and give the prospects for the future at the LHC. Of special interest is the exclusive production of Higgs boson and heavy objects (W , top, stop pairs) which will require a better understanding of diffractive events and the link between ep and hadronic colliders, as w...
