Neutrino mass and lepton number violation in the Little Higgs model
We study lepton number violation in Little Higgs model and find that the
choice of putting triplet Higgs vev equal to zero so as not to have any tree
level neutrino Majorana mass is not natural in the sense that such a term is
generated at the one loop level. We investigate the contribution of exotic
lepton number violating terms on neutrinoless double beta decay, K meson decay
and on trilepton production in -N scattering.Comment: 6 pages including 3 eps figures, talk given at PASCOS-05 held at

Effects of curvature and interactions on the dynamics of the deconfinement phase transition
We study the dynamics of first-order cofinement-deconfinement phase
transition through nucleation of hadronic bubbles in an expanding quark gluon
plasma in the context of heavy ion collisions for interacting quark and hadron
gas and by incorporating the effects of curvature energy. We find that the
interactions reduce the delay in the phase transition whereas the curvature
energy has a mixed behavior. In contrast to the case of early Universe phase
transition, here lower values of surface tension increase the supercooling and
slow down the hadronization process. Higher values of bag pressure tend to
speed up the transition. Another interesting feature is the start of the
hadronization process as soon as the QGP is created.Comment: LaTeX, 17 pages including 14 postscript figure
Lepton number violation in Little Higgs model
In this note we examine the constraints imposed by muon anomalous magnetic
moment () and on lepton number violating
(LNV) couplings of the triplet Higgs in Little Higgs (LH) model.Comment: revtex4.0 file, 5 pages including 8 eps figures, version to appear in
