    Abstract We have recalculated the nucleon pole diagram for pionic disintegration of deuterium, including the effects of the small components of the interacting nucleon by keeping all four invariants of the Blankenbecler and Cook vertex. We obtain the leading contributio...

    We give the list of all positive energy UIR's of the conformal superalgebra su(2, 2N). They are realized as subrepresentations of elementary representations. The latter are induced from irreducible finite-dimensional Lorentz and su(N) representations on spaces of functi...

    The Sivers mechanism for the single-spin asymmetry in unpolarized lepton scattering from a transversely polarized nucleon is driven by the orbital angular momentum carried by its quark and gluon constituents, combined with QCD final-state interactions. Both quark and gl...

    The mass difference between K1o and K2o mesons was determined. K1o-mesons were produced as a result of coherent regeneration in Al plates placed in a Ko-beam. The intensity if Ko → π± decay was measured at different thickness of the regenerator. Ko → π± decays were dete...

    Abstract A new statistical description of hardonic charged-particle multiplicity distributions is presented, which takes into account the associated neutral multiplicity and charge conservation. A simple gamma distribution is used to generate fictitious intermediate neu...

    We investigate the eigenvalue spectrum of the staggered Dirac matrix in SU(3) gauge theory and in full QCD on a $6^3\times 4$ lattice. As a measure of the fluctuation properties of the eigenvalues, we study the nearest-neighbor spacing distribution $P(s)$ for various va...
