Radion and Higgs Signals in Peripheral Heavy Ion Collisions at the LHC
We investigate the sensitivity of the heavy ion mode of the LHC to Higgs
boson and Radion production via photon-photon fusion through the analysis of
the processes photon to photon photon, photon photon to b anti-b, and photon
photon to g g in peripheral heavy ion collisions. We suggest cuts to improve
the Higgs and Radion signal over standard model background ratio and determine
the capability of LHC to detect these particles production.Comment: 16 pages, 8 eps figures. admin note: text overlap with

New Higgs Interactions in ZZ\gamma and Z\gamma\gamma Production
The effect of new operators that only modify the bosonic couplings of the
Higgs boson, without altering the WW\gamma or WWZ three-point functions, are
examined in the e+e- -> ZZ\gamma and Z\gamma\gamma processes. We analyse the
constraints on these interactions that can be imposed by the LEP II collider at
CERN and at the Next Linear Collider.Comment: 7 pages, RevTeX, 3 postscript figure
Anomalous Higgs Couplings
We review the effects of new effective interactions on the Higgs boson
phenomenology. New physics in the electroweak bosonic sector is expected to
induce additional interactions between the Higgs doublet field and the
electroweak gauge bosons leading to anomalous Higgs couplings as well as to
anomalous gauge-boson self-interactions. Using a linearly realized invariant effective Lagrangian to describe the bosonic sector of
the Standard Model, we review the effects of the new effective interactions on
the Higgs boson production rates and decay modes. We summarize the results from
searches for the new Higgs signatures induced by the anomalous interactions in
order to constrain the scale of new physics in particular at CERN LEP and
Fermilab Te vatron colliders.Comment: 35 pages, latex using epsfig.sty psfig.sty and axodraw.sty, 16

New Higgs couplings at e^+ e^- and hadronic colliders
We examine the potentiality of both CERN LEP and Fermilab Tevatron colliders to establish bounds on new couplings involving the bosonic sector of the standard model. We pay particular attention to the anomalous Higgs interactions with , and . A combined exclusion plot for the coefficients of different anomalous operators is presented. The sensitivity that can be achieved at the Next Linear Collider and at the upgraded Tevatron is briefly discussed
