Query: Bounds on Compositeness from Neutrinoless Double Beta Decay   Assuming the existence of a heavy Majorana neutral particle arising from a
composite model scenario we discuss the constraints imposed by present
experimental limits of half-life neutrinoless double beta decay
$(0\nu\beta\beta ) $ measurements on the coupling of the heavy composite
neutrinos to the gauge bosons. For neutrino masses $M_N = 1 $ TeV we obtain a
rather weak lower bound on the compositeness scale: $\Lambda \ge 0.23 $ TeV.
