Vacuum decay and internal symmetries
Alexander Kusenko, Kimyeong Lee, Erick J. Weinberg
We study the effects of internal symmetries on the decay by bubble nucleation of a metastable false vacuum. The zero modes about the bounce solution that are associated with the br…
Is the vacuum stable?
Alexander Kusenko, Paul Langacker
The experimental data, as well as theoretical considerations allow (and, in some cases, require) the Universe at present to rest in a false vacuum, whose approximate stability impo…
The origin of pulsar velocities
Alexander Kusenko, Gino Segre
We have recently proposed an explanation for the birth velocities of pulsars as resulting from asymmetries due to neutrino oscillations in the cooling protoneutron star. A specific…
Color and charge breaking minima in the MSSM
Alexander Kusenko
The scalar potential of theories with broken supersymmetry can have a number of local minima characterized by different gauge groups. Symmetry properties of the physical vacuum con…
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…
