106. Gauged B-L symmetry and leptogenesis from axion inflation

Kohei Kamada (HIAS UCAS)

In the context of axion inflation, inflaton can couple to gauge fields through the Chern-Simons coupling. This coupling gives rise to an instability of helical U(1) gauge fields. If the B-L symmetry in the Standard Model is gauged, at the end of inflation through the chiral anomaly we have helical B-L magnetic fields and B-L asymmetry in the visible and sterile sector, while the total B-L...

88. Electroweak Precision Data as a Gateway to Light Higgsinos

We investigate the prospects of probing weak-scale higgsinos through electroweak precision measurements at a future $e^+ e^-$ collider. In the Minimal Supersymmetric Standard Model, higgsinos mix with winos and binos after electroweak symmetry breaking, forming charginos and neutralinos. These states contribute to electroweak precision observables, which can be measured with high accuracy at...
