Improved description of charged Higgs boson production at hadron colliders
We present a new method for matching the two twin-processes gb → Ht and gg → Htb in Monte Carlo event generators. The matching is done by defining a double-counting term, which is used to generate events that are subtracted from the sum of the two twin-processes. In this way we get a smooth transition between the collinear region of phase space, which is best described by gb → Ht, and the hard ...
متن کاملAn improved description of charged Higgs boson production
Many extensions of the Standard Model predict the existence of charged Higgs bosons. In order to be able to find those particles, an accurate description of their production is needed. In Monte Carlo simulations of charged Higgs boson production at hadron colliders, the two tree-level processes gb → Ht and gg → Htb are used. Since those processes overlap in the collinear region of the phase-spa...
متن کاملPair production of charged MSSM Higgs bosons by gluon fusion
The production of pairs of charged Higgs bosons as predicted by the minimal supersymmetric standard model (MSSM) via the gluon fusion mechanism is investigated. The amplitudes at the leading one-loop order for the parton process gg → H+H− are calculated with the complete set of MSSM particles. Numerical results are presented for the cross section of the inclusive hadron process pp → gg → H+H−+X...
متن کاملStudying Higgs Bosons by Top Pair Production at Photon Colliders
where φ denotes a spinless boson H or A (H and A are the CP-even and CPodd Higgs bosons respectively.), the γγφ vertex parameter bγ generally has complex phase even in CP invariant theories of the Higgs sector. Because the imaginary part of bγ is a sum of the contribution from the φ decay modes into charged particles whereas the real part receives contribution from all the charged particles, we...
متن کاملClassical Description of Pair Production
It is shown that the classical description of pair production effect is possible, i.e. one can describe pair production without a reference to quantum principles. Pair production appears at statistical description of stochastic relativistic particles. There is a special force field which is responsible for pair production. This field is a reasonable consequence of quantum stochasticity. Conside...
