The Stern-Gerlach Experiment and the Electron Spin
Sandip Pakvasa
The full story of the Stern-Gerlach experiment and its reception, interpretation and final understanding has many unexpected surprises. Here, we review the history and the context…
Big Bang Nucleosynthesis in the presence of sterile neutrinos with altered dispersion relations
Elke Aeikens, Heinrich Päs, Sandip Pakvasa +1
Big Bang Nucleosynthesis imposes stringent bounds on light sterile neutrinos mixing with the active flavors. Here we discuss how altered dispersion relations can weaken such bounds…
Light Sterile Neutrinos, Lepton Number Violating Interactions and the LSND Anomaly
K. S. Babu, Douglas W. McKay, Irina Mocioiu +1
We develop the consequences of introducing a purely leptonic, lepton number violating non-standard interaction (NSI) and standard model neutrino mixing with a fourth, sterile neutr…
Lorentz Invariance Violation and IceCube Neutrino Events
Gaurav Tomar, Subhendra Mohanty, Sandip Pakvasa
The IceCube neutrino spectrum shows a flux which falls of as for sub PeV energies but there are no neutrino events observed above PeV. In particular the Glashow r…
Nonstandard Higgs decays in the E6 inspired SUSY models
R. Nevzorov, S. Pakvasa
We consider the exotic decays of the SM-like Higgs state within the E6 inspired supersymmetric (SUSY) models. In these models the lightest SUSY particle (LSP) can be substantially…
Flavor ratios of extragalactical neutrinos and neutrino shortcuts in extra dimensions
Elke Aeikens, Heinrich Päs, Sandip Pakvasa +1
The recent measurement of high energy extragalactic neutrinos by the IceCube Collaboration has opened a new window to probe non-standard neutrino properties. Among other effects, s…
