Improving the discovery potential of charged Higgs bosons at Tevatron Run 2
By exploiting the full process , in place of the
standard Monte Carlo procedure of factorising production and decay, followed by , we show how to improve the
discovery reach of the Tevatron (Run 2) in charged Higgs boson searches, in the
large region. This is achieved in conjunction with dedicated cuts
on a `transverse mass' distribution sensitive to the Higgs boson mass and to
`polarisation' effects in the decay channel.Comment: 12 pages, LaTeX, 5 figures (one figure added, discussion slightly

Event-shape selection cuts for supersymmetry searches at the LHC with 7 TeV energy
We investigate the prospects of supersymmetry searches at the LHC with 7 TeV
energy. A new set of selection cuts is proposed based on event shapes to
control backgrounds. Our preliminary studies show that it is possible to
minimize backgrounds to a significantly low level and conservative estimate
suggests that the mass reach can be extended to 1.1 TeV for luminosity
1/fb with a reasonable signal-to-background ratio.Comment: 5 pages, 2 figures, title changed, typos are corrected, text is

Detection prospects of light pseudoscalar Higgs boson at the LHC
The discovery potential of light pseudo scalar Higgs boson for the mass range
10-60 GeV is explored. In the context of the next-to-minimal supersymmetric
standard(NMSSM) model, the branching fraction of light pseudo scalar Higgs
boson decaying to a pair of photon can be quite large. A pair of light pseudo
scalar Higgs boson produced indirectly through the standard model Higgs boson
decay yields multiple photons in the final state and the corresponding
production rate is restricted by ATLAS data. Discussing the impact of this
constraint in the NMSSM, the detection prospects of light pseudoscalar Higgs
boson in the channel consisting of at least three photons, a lepton and missing
transverse energy are reported. It is observed that the possibilities of
finding the pseudoscalar Higgs boson for the above mass range are promising for
an integrated luminosity with moderate
significances, which can reach to more than 5 for higher luminosity
options.Comment: 24 pages, 4 figures, updated reference
