چکیده

The pair production cross section for scalar and vector leptoquarks at ep colliders is calculated for the case of photon{gluon fusion. In a model independent analysis we consider the most general C and P conserving couplings of gluons and photons to both scalar and vector leptoquarks described by an eeective low{energy Lagangian which obeys U (1) em SU (3) c invariance. Numerical predictions are given for the kinematical regime at HERA and LEP LHC.

It is shown that a satisfactory explanation of the ratio of the rates of the 0 reactions 3 He(π − , nn) and 3 He(π − , np) for stopped pions is obtained once the effect of the short range two-nucleon components of the axial charge operator for the nuclear system is taken into account. By employing realistic models for the nucleon-nucleon interaction in the construction of these components of th...

We compute an array of Standard Model Higgs boson (H) signals and backgrounds for a possible upgrade of the Tevatron to √ s = 4 TeV. Taking m t ≥ 140 GeV, and assuming a total accumulated luminosity of L = 30 fb −1 , we find that a Standard Model Higgs boson with m H < ∼ 110 GeV could almost certainly be detected using the W ± H → lνbb mode. A Higgs boson with mass between ∼ 120 GeV and ∼ 140 G...
