Search for long-lived Wino-Bino annihilation model


The target is a neutral wino has a macroscopic decay length in a wide range of parameter space.

This characteristic feature could be observed as a displaced vertex plus missing transverse energy.

In this model, Wino decays into Bino and Z/h, and Z/h decays into a pair of quarks.

Bino is assumed as the LSP and can be the candidate of the dark matter.

MC truth study is going on with private project based on the software tutorial.

The framework will be moved to the FactoryTools.
