The minimal NCSM contribution of a direct photon production at the Tevatron and LHC is obtained and the phenomenological implications are discussed. Some behaviors are discussed. It is shown that the effect of the space-time noncommutativity becomes important at very high energies leading to a violation of unitarity. [ABSTRACT FROM AUTHOR]

A make a qualitative study of the KT effect in the Higgs associative production with a W vector boson at the LHC. The kinematics are presented and the generalized form of the cross section is obtained. [ABSTRACT FROM AUTHOR]

The helecity amplitudes of the subprocess gg → γγ via scalar unparticles intermediate states are calculated. The differential cross section is compared to that of the standard model. Phenomenological implications are also discussed. [ABSTRACT FROM AUTHOR]

The contribution of the pure NCG forbidden subprocess gg → ZHis calculated. It is shown that the cross section becomes important at the LHC energies and depends strongly on the choice of the noncommutativity parameter. Because of the gluons luminosity inside the proton, it becomes comparable to that of the commutative standard model subprocess qq ZHfor reasonable values of the NCG parameter. [ABSTRACT FROM AUTHOR]

A pure NCG gluon fusion contribution to the Higgs production at large hadron colliders is discussed. It is shown that the NCG results become relevant at very high energies. This can be a good signal for the space-time non commutativity events. [ABSTRACT FROM AUTHOR]
