CP-violating correlations between lepton-charge and jet-charge in events

Jet Charge

First Result of Net-Charge Jet-Correlations from STAR

We presented results on azimuthal correlation of net-charge with high pT trigger particles. It is found that the net-charge correlation shape is similar to that of total-charge. On the near-side, the net-charge and total-charge pT spectra have similar shape and both are harder than the inclusives. On the away-side, the correlated spectra are not much harder than the inclusives, and the net-char...

Charge-conjugation violating neutrino interactions in supernovae

The well known charge conjugation violating interactions in the Standard Model increase neutrinoand decrease anti-neutrinonucleon cross sections. This impacts neutrino transport in core collapse supernovae through “recoil” corrections of order the neutrino energy k over the nucleon mass M . All k/M corrections to neutrino transport deep inside a protoneutron star are calculated from angular int...

Cp Violating Lepton Asymmetries in Left-right Models

Lepton charge asymmetries can be used as an alternative means of searching for new physics. They are interesting because they are small in the Standard Model and therefore, necessarily evidence new physics. In this work we explore the use of lepton asymmetries as a probe of the flavour structure of the left-right symmetric model with spontaneous CP violation. We find that new physics may enhanc...
