Lepton-Neutron Bound States

by R. A. Alanakyan , 1999
"... We consider lepton-neutron (and lepton-antineutron) bound states and resonances which appear due to spin-spin,spin-orbital interactions,neutron polarization by muon. Our analis is also true for any system which include one charge and one neutral particle with finite size e.g. π 0 µ ±-bound states.We ..."

Quaternionic bound states

by Stefano De Leo , Gisele C Ducati - Journal of Physics A , 2005
"... Abstract We study the bound-state solutions of vanishing angular momentum in a quaternionic spherical square-well potential of finite depth. As in standard quantum mechanics, such solutions occur for discrete values of energy. At first glance, it seems that the continuity conditions impose a very r ..."

Bound states at lowest order in �

by Paul Hoyer , 909
"... Abstract: Bound states poles in scattering amplitudes are generated by the divergence of the perturbative series due to enhanced Coulomb scattering near thresholds. This suggests to organize bound state calculations according to an expansion in �, i.e., in the number of loops. I study QED and QCD bo ..."

On the Equivalence of Bound State Solutions

by Ulf Gran, Mikkel Nielsen , 2001
"... In this paper we show the equivalence of various (non-threshold) bound state solutions of branes, or equivalently branes in background potentials, in ten- and eleven-dimensional supergravity. We compare solutions obtained in two very different ways. One method uses a zero mode analysis to make an An ..."

Renormalization Flow of Bound States

by Holger Gies A, Christof Wetterich B , 2001
"... A renormalization group flow equation with a scale-dependent transformation of field variables gives a unified description of fundamental and composite degrees of freedom. In the context of the effective average action, we study the renormalization flow of scalar bound states which are formed out of ..."

On the Bound States of Matrix Strings

by Vatche Sahakian
"... We investigate excitations in Matrix Theory on T 2 corresponding to bound states of strings. We demonstrate the Dirichlet aspect of R-R charged vacua through a non-trivial connection between the U(1) and SU(n) sectors of the matrix SYM. ..."

Vacuum-Bounded States and the Entropy of

by Ken D. Olum, Alan H. Guth, F. Koster, Ken D. Olum , 1997
"... We call a state “vacuum bounded ” if every measurement performed outside a specified interior region gives the same result as in the vacuum. We compute the maximum entropy of a vacuum-bounded state with a given energy for a one-dimensional model, with the aid of numerical calculations on a lattice. ..."

Bound States and Instabilities of Vortices

by Michael Goodb, Mark Hindmarsh , 1995
"... We examine the spectrum of small perturbations around global and local (gauge) abelian vortices, using simple numerical matrix techniques. The results are of interest both for cosmic strings and for their condensed matter analogues, superfluid and superconductor vortices. We tabulate the instabiliti ..."

SEMIRELATIVISTIC TREATMENT OF BOUND STATES

"... This talk reviews several aspects of the “semirelativistic ” description of bound states by the spinless Salpeter equation (which represents the simplest equation of motion incorporating relativistic effects) and, in particular, presents or recalls some very simple and elementary methods which allow ..."
