  The existence of mirror partners of Standard-Model fermions offers a viable
alternative to a fundamental BEH mechanism, with the coupling corresponding to
the gauged mirror generation symmetry becoming naturally strong at energies
around 1 TeV. The resulting non-perturbative processes produce dynamical
katoptron masses which might range from 0.1 to 1.15 TeV in a way circumventing
usual problems with the S parameter. Moreover, they create mirror mesons
belonging in two main groups, with masses differing from each other
approximately by a factor of six and which might range approximately from 0.1
to 2.8 TeV. Since the corresponding phenomenology expected at hadron colliders
is particularly rich, some interesting mirror-meson cross-sections are
presented, something that might also lead to a deeper understanding of the
underlying mirror fermion structure. Among other findings, results in principle
compatible with indications from LHC concerning decays of new particles to two
photons are analyzed.
