Query: Is leptogenesis falsifiable at LHC?   It is well known that the leptogenesis mechanism offers an attractive
possibility to explain the baryon asymmetry of the universe. Its particular
robustness however comes with one major difficulty: it will be very hard if not
impossible to test experimentally in a foreseeable future, as most of the
mechanics typically takes place at high energy or results from suppressed
interactions, without unavoidable low-energy implications. An alternate
approach is taken by asking: can it be at least falsified? We show that
possible discoveries at current and future colliders, most notably that of
right-handed gauge interactions, would indeed forbid at least the "canonical"
leptogenesis mechanisms, namely those based on right-handed neutrino decay.
General lower bounds for successful leptogenesis on the mass of the
right-handed gauge boson W_R are given. Other possibilities to falsify
leptogenesis, including from the observation of a Z', are also considered.
