Descripción
A search for new particles has been conducted using events with two high
transverse momentum ( p T) τ leptons that decay
hadronically, at least two high- p T jets, and missing
transverse energy from the τ lepton decays. The analysis is
performed using data from proton-proton collisions, collected by the CMS
experiment in 2015 at √{s}=13 TeV, corresponding to an integrated
luminosity of 2.1 fb-1. The results are interpreted in two
physics models. The first model involves heavy right-handed neutrinos,
Nℓ ( ℓ = e , μ, τ), and right-handed charged
bosons, WR, arising in a left-right symmetric extension of
the standard model. Masses of the WR boson below 2.35 (1.63)
TeV are excluded at 95% confidence level, assuming the N τ
mass is 0.8 (0.2) times the mass of the WR boson and
that only the N τ flavor contributes to the
WR decay width. In the second model, pair production of
third-generation scalar leptoquarks that decay into ττbb is
considered. Third-generation scalar leptoquarks with masses below 740
GeV are excluded, assuming a 100% branching fraction for the leptoquark
decay to a τ lepton and a bottom quark. This is the first search at
hadron colliders for the third-generation Majorana neutrino, as well as
the first search for third-generation leptoquarks in the final state
with a pair of hadronically decaying τ leptons and jets. [Figure not
