### Description

An algorithm for reconstruction of the Higgs mass in $H \rightarrow \tau\tau$ decays is presented. The algorithm computes for each event a likelihood function $P(M_{\tau\tau})$ which quantifies the level of compatibility of a Higgs mass hypothesis $M_{\tau\tau}$, given the measured momenta of visible tau decay products plus missing transverse energy reconstructed in the event. The algorithm is used in the CMS $H \rightarrow \tau\tau$ analysis. It is found to improve the sensitivity for the Standard Model Higgs boson in this decay channel by about $30\%$.
