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.Comment: Plain Latex file, 15 pages; 3 figures appended as a uuencoded file; misprint corrected in titlepag

The Gauge-Bethe Correspondence and Geometric Representation Theory

The Gauge/Bethe correspondence of Nekrasov and Shatashvili relates the spectrum of integrable spin chains to the ground states of supersymmetric gauge theories. Up to now, this correspondence has been an observation; the underlying reason for its existence remaining elusive. We argue here that geometrical representation theory is the mathematical foundation of the Gauge/Bethe correspondence, and it provides a framework to study families of gauge theories in a unified way.Comment: 8 page
