Experimental signatures of supersymmetric dark-matter Q-balls
Alexander Kusenko, Vadim Kuzmin, Mikhail Shaposhnikov +1
Theories with low-energy supersymmetry predict the existence of stable non-topological solitons, Q-balls, that can contribute to dark matter. We discuss the experimental signatures…
Supersymmetric Q-balls as dark matter
Alexander Kusenko, Mikhail Shaposhnikov
Supersymmetric extensions of the standard model generically contain stable non-topological solitons, Q-balls, which carry baryon or lepton number. We show that large Q-balls can be…
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…
Q-balls in the MSSM
Alexander Kusenko
Q-balls are generically present in models with softly broken low-energy supersymmetry. We discuss the properties of these non-topological solitons, which can precipitate a new kind…
New physics in a nutshell, or Q-ball as a power plant
Gia Dvali, Alexander Kusenko, Mikhail Shaposhnikov
Future experiments may discover new scalar particles with global charges and couplings that allow for solitonic states. If the effective potential has flat directions, the scalar V…
Phase transitions precipitated by solitosynthesis
Alexander Kusenko
Solitosynthesis of Q-balls in the false vacuum can result in a phase transition of a new kind. Formation and subsequent growth of Q-balls via the charge accretion proceeds until th…
Solitons in the supersymmetric extensions of the Standard Model
Alexander Kusenko
All supersymmetric generalizations of the Standard Model allow for stable non-topological solitons of the Q-ball type which may have non-zero baryon and lepton numbers, as well as…
Small Q balls
Alexander Kusenko
We develop an adequate description of non-topological solitons with a small charge, for which the thin-wall approximation is not valid. There is no classical lower limit on the cha…
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…
