Measurement of tan beta in associated t H^\pm Production in gamma gamma Collisions
M. A. Doncheski, Stephen Godfrey, Shouhua Zhu
The ratio of neutral Higgs field vacuum expectation values, tan beta, is one of the most important parameters to determine in type-II Two-Higgs Doublet Models (2HDM), specifically…
Extra-dimensional gravity and dijet production at gamma gamma colliders
M. A. Doncheski, R. W. Robinett
In this note, we consider dijet production at gamma gamma colliders as a probe of recently proposed, large extra-dimensional gravity models. The exchange of virtual, spin-2 gravito…
Radiation zeros and scalar particles beyond the standard model
M. A. Doncheski, R. W. Robinett
Standard radiation zeros arise from the factorization properties of tree-level amplitudes involving a massless photon and can occur when all charged particles in the initial and fi…
Leptoquark production in ultrahigh-energy neutrino interactions revisited
M. A. Doncheski, R. W. Robinett
The prospects for producing leptoquarks (LQs) in ultrahigh-energy (UHE) neutrino nucleon collisions are re-examined in the light of recent interpretations of HERA data in terms of…
Fragmentation production of doubly heavy baryons
M. A. Doncheski, J. Steegborn, M. L. Stong
Baryons with a single heavy quark are being studied experimentally at present. Baryons with two units of heavy flavor will be abundantly produced not only at future colliders, but…
Spin-Spin Asymmetries in Large Transverse Momentum Higgs Boson Production
M. A. Doncheski, R. W. Robinett, L. Weinkauf
We examine the spin-dependence of standard model Higgs boson production at large transverse momentum via the processes , , and $q\overline…
