A Scalar Doublet at the Tevatron?
Gino Segre, Boris Kayser
We propose a particularly simple explanation of the W+dijet excess reported by the CDF collaboration. No symmetries beyond those of the standard model are necessary, and the only n…
Leptogenesis at the Electroweak Scale
Boris Kayser, Gino Segre
In this note we propose a model of leptogenesis in which the scale for the mass of the necessary heavy neutral lepton is similar to the scale of electroweak symmetry breaking.
Implications of Gauge Unification for Time Variation of the Fine Structure Constant
Paul Langacker, Gino Segre, Matthew J. Strassler
Unification of the gauge couplings would imply that time variations of the fine structure constant are accompanied by calculable and very significant time variations in the QCD sca…
Cyclotron Emissivity in the Early Universe
Gino Segre
Primordial magnetic fields present between the eras of neutrino decoupling and of positron-electron annihilation can lead to the emission of neutrino-anti neutrino pairs or axions…
Reply to Comment on "Pulsar velocities and neutrino oscillations"
Alexander Kusenko, Gino Segre
We have recently proposed an explanation for the birth velocities of pulsars based on neutrino oscillations (hep-ph/9606428). One of the quantities, dN/dT, was evaluated in the app…
Neutral current induced neutrino oscillations in a supernova
Alexander Kusenko, Gino Segre
Neutral currents induced matter oscillations of electroweak-active (anti-)neutrinos to sterile neutrinos can explain the observed motion of pulsars. In contrast to a recently propo…
Velocities of pulsars and neutrino oscillations
Alexander Kusenko, Gino Segre
Neutrino oscillations, biased by the magnetic field, alter the shape of the neutrinosphere in a cooling protoneutron star emerging from the supernova collapse. The resulting anisot…
Phase Transitions and Vacuum Tunneling Into Charge and Color Breaking Minima in the MSSM
Alexander Kusenko, Paul Langacker, Gino Segre
The scalar potential of the MSSM may have local and global minima characterized by non-zero expectation values of charged and colored bosons. Even if the true vacuum is not color a…
Unstable particle mixing and CP violation in weak decays
Jiang Liu, Gino Segrè
We discuss unstable particle mixing in CP-violating weak decays. It is shown that for a completely degenerate system unstable particle mixing does not introduce a CP-violating part…
Re-Examination of Generation of Baryon and Lepton Number Asymmetries by Heavy Particle Decay
Jiang Liu, Gino Segre
It is shown that wave function renormalization can introduce an important contribution to the generation of baryon and lepton number asymmetries by heavy particle decay. These term…
