Strategies for measurement of lifetimes for long-lived particles

People interested : Biplob Bhattacharjee, Shankha Banerjee, Andreas Goudelis, Bjorn Hermann, Dipan Sengupta.

Question : Devising strategies to measure the lifetime of long lived particles ?

Fix minimal set of benchmark models to calculate lifetimes. Calculate lifetimes for benchmark models.

Possibilities, ex : leptons, jets, photons .. Classification: based on final states and localization of the decay vertex. Ex , $H \to \phi \phi, \phi \to \mu^{+} \mu^{-} $.

Dependence of Spin, production Modes ..

Difficulties :

a) Uncertainties in the reconstruction of secondary vertex.

b) Decay inside Ecal/Hcal.

c) Missing Energy in the decay.

d) Estimation of backgrounds.
