Description
Reconstruction of di-$\tau$ mass in a faster and more accurate way than the existing methods is crucial to test any theory involving Higgs boson and Z boson which are decaying to $\tau^+ \tau^-$. However, it is an arduous task due to existence of neutrinos as decay product of each $\tau$ lepton which are invisible to detectors at LHC.
The present ongoing work aims at obtaining a di-$\tau$ mass estimator using ML techniques. Its use in the CMS MSSM $H\to\tau\tau$ analysis on the full Run II will be discussed.
