42. Same-Sign Tetra-Leptons from Type II Seesaw

Eung Jin Chun (Korea Institute for Advanced Study)

06/05/2013, 16:30

In the type II seesaw mechanism introducing a hypercharged triplet boson, the neutral components can exhibit a novel phenomenon of the triplet-antitriplet oscillation resulting in same-sign tetra-lepton final states at the LHC. After discussing the production cross-sections in the parameter space of the mass splitting among triplet components and the triplet vacuum expectation value, we...

29. Inverse Seesaw Neutrino Signatures at LHC and ILC

Mr Arindam Das (University of Alabama)

We study the collider signature of pseudo-Dirac heavy neutrinos in the inverse seesaw scenario, where the heavy neutrinos with mass at the electroweak scale can have sizable mixings with the Standard Model neutrinos, while providing the tiny light neutrino masses by the inverse seesaw mechanism. Based on a simple, concrete model realizing the inverse seesaw, we fix the model parameters so as...

122. Constraining the Interactions of the Neutrino with OscSNS

Chen Sun (V)

Our research is based on the white paper of OscSNS, a neutrino oscillation experiment proposed to use Spallation Neutron Source (SNS) in Oak Ridge National Laboratory(ORNL). We used the elastic scattering between neutrinos and electrons to constrain the non-standard interaction coupling constant not specified to one single model, as well as to constrain the sin^2 \theta_W.

168. Ultra-high energy cosmic rays and neutrinos at the Pierre Auger Observatory

Pedro Facal San Luis (University of Chicago)

06/05/2013, 17:15

The Pierre Auger Observatory in Malargue Argentina is dedicated to the study of ultra-high energy cosmic rays, using a hybrid detector (combination of fluorescence and surface detectors) of unprecendent size and precision. I will review the latest results of the Observatory, like UHECR spectrum and composition, with special emphasis on the ones relevant to the particle physics community such...

125. Neutrino-nucleon scattering

Preet Sharma (University of Mississippi)

06/05/2013, 17:30

We discuss the effects of W-prime and the charged Higgs contributions to Quasi-Elastic scattering, Resonance scattering and Deep-Inelastic scattering in the neutrino-nucleon scattering. The neutrino mixing angles δ23 and δ13 are given in all the three cases and the the new physics contribution is also studied. We have also included the effects of the polarized lepton to all the above cases

11. An Upper Limit on the Neutron-Antineutron Oscillation Time

Dr P. S. Bhupal Dev (University of Manchester)

06/05/2013, 17:45

A new scenario for baryogenesis, termed post-sphaleron baryogenesis (PSB), has been proposed wherein the baryon asymmetry of the universe is produced below the electroweak phase transition temperature after the sphaleron processes have gone out of equilibrium. This mechanism arises naturally in quark-lepton unied models. A necessary consequence of this scenario is the baryon number violating...
