   Finite Volume Effects in Weak Hadronic Decays

   C.-J.D. Lin🇬🇧 · G. Martinelli🇮🇹 · C.T. Sachrajda🇬🇧 · M. Testa🇮🇹

   In this talk we discuss finite-volume computations of two-body hadronic decays below the inelastic threshold (e.g. $K\to \pi \pi$ decays). In particular we show how the relation between finite-volume matrix elements and physical amplitudes, recently derived by Lellouch and Lüscher, can be extended to all elastic states under the inelastic threshold. We also provide a derivation of the Lüscher quantization condition directly in quantum field theory.

   Towards the lattice study of M-theory (II)

   P.Bialas🇵🇱 · J.Wosiek🇵🇱

   We present new results of the quenched simulations of the reduced D=4 supersymmetric Yang - Mills quantum mechanics for larger gauge groups SU(N), 2<N<9. The model, studied at finite temperature, reveals existence of the two distinct regions which may be precursors of a black hole and the elementary D0 branes phases of M-theory conjectured in the literature. Present results for higher groups confirm the picture found already for N=2. Similar behaviour is observed in the preliminary simulations for the D=6 and D=10 models.
