Enhanced Three-Body Decay of the Charged Higgs Boson
Ernest Ma, D. P Roy, Jose Wudka
If the charged Higgs boson H+ exists with mh < mt + mb, the conventional expectation is that it will decay dominantly into c s-bar and tau+ nu-tau. However, the three-body decay mo…
New Physics from HERA?
D. P. Roy
The H1 and ZEUS experiments at the HERA collider at Hamburg have recently reported some anomalous hard-scattering events, which could be indicative of new physics beyond…
The Intrinsic Gluon Component of the Nucleon
Paul Hoyer, D. P. Roy
Using an intrinsic parton model we estimate the rough shape and size of the intrinsic gluon component of the nucleon, corresponding to an energy scale of the order $\lqcd$. It…
Constraints on the charged Higgs sector from the CDF Top quark data
D. P. Roy
The top quark data in the lepton plus channel offers a viable probe for the charged Higgs boson signal. We have analysed the recent Collider Detector at Fermilab (CDF) data in…
Light Higgsino Dark Matter
M. Drees, M M. Nojiri, D. P. Roy +1
We re-investigate the question whether a light higgsino-like neutralino is a viable Dark Matter candidate. To this end we compute the dominant one-loop corrections to the masses of…
