[en] Various ways of obtaining a lower bound on the mass of the second charged weak boson required in a left-right symmetric gauge theory are investigated. They are all based on hadronic processes, in an effort to get more model-independent answers. From the K_L - K_S mass difference, the limit obtained is M(W₂) greater than or equal to 370 GeV, if one neglects a possible top quark influence. From non-leptonic hyperon decays, one can only derive a bound on the angle zeta which mixes the couplings of the primarily left- and right-handed W-bosons: parallel bar zeta parallel bar less than or equal to 1 to 2%. From hadronic K-decays, one obtains a limit M(W₂) greater than or equal to 280 GeV, roughly similar to that found by Beg et al. from leptonic charged current data, but not restricted by assumptions about neutrino masses
