Description
A search for events containing two high-transverse-momentum tau leptons
has been performed with the ZEUS detector at HERA, using the data sample
collected between 2004 and 2007, corresponding to 0.36 fb^-1. At least
one of the tau candidates is required to decay hadronically, while the
second tau is required to decay either in an electron or in hadrons. The
number of observed tau pairs has been compared with the prediction from
the Standard Model, where the largest contribution is expected from
Bethe-Heitler interactions. Possible deviations from the Standard Model,
especially at high invariant masses of the tau pair, have been searched
for.
