The results of trinucleon bound state calculations using with the recent version (Graz II) of Graz separable N IV potentials are presented. Graz II potentials frt not only the latest phenomonological phases rather accurately in the energy range 0 6OOAfeV(Z&), but. also provide a correct description of the deuteron data (l&,pd, Q, q). Their of&shell behavior is similar to that of the Paris poten...

We considered the kaon absorption from atomic states into nucleus. We found that the nuclear density probed by the atomic kaon significantly depends on the kaon orbit. Then, we reexamined the meanings of the observed strengths of one–body and two–body kaon absorption, and investigated the effects to the formation spectra of kaon bound states by in–flight (K−, p) reactions. As a natural conseque...

The relativistic mean field (RMF) model is applied to a system of nucle-ons and a ¯ K meson, interacting via scalar and vector boson fields. The model incorporates the standard RMF phenomenology for bound nucleons and, for the ¯ K meson, it relates to low-energy ¯ KN and K − atom phenomenology. Deeply bound ¯ K nuclear states are generated dynamically across the periodic table and are exhibited...

We present a mathematically rigorous method suitable for solving three-body bound state and scattering problems when the inter–particle interaction is of a hard–core nature. The proposed method is a variant of the Boundary Condition Model and it has been employed to calculate the binding energies for a system consisting of three 4He atoms. Two realistic He–He interactions of Aziz and collaborat...

We discuss recent lattice results on in-medium properties of hadrons and focus on thermal properties of heavy quark bound states. We will clarify the relation between heavy quark free energies and potentials used to analyze the melting of heavy quark bound states. Furthermore, we present calculations of meson spectral functions which indicate that the charmonium ground states, J/ψ and ηc, persi...

We show that all supersymmetric Type IIA D-branes can be constructed as bound states of a certain number of unstable non-supersymmetric Type IIA D9-branes. This string-theoretical construction demonstrates that D-brane charges in Type IIA theory on spacetime manifold X are classified by the higher K-theory group K(X), as suggested recently by Witten. In particular, the system of N D0-branes can...

In theories with TeV scale quantum gravity the standard model particles live on a brane propagating in large extra dimensions. Branes may be stabilized at large (sub-millimeter) distances from each other, either due to weak Van der Waals type interactions, or due to an infrared analog of Witten’s inverse hierarchy scenario. In particular, this infrared stabilization may be responsible for a lar...

A detailed study is made of four dimensional SU(2) gauge theory with static adjoint “quarks” in the context of string breaking. A tadpole-improved action is used to do simulations on lattices with coarse spatial spacings as, allowing the static potential to be probed at large separations at a dramatically reduced computational cost. Highly anisotropic lattices are used, with fine temporal spaci...

We searched for the existence of weakly bound He–He–H, He–He–H− and He–H– H molecules where the binding energies are expected to be of the order of degrees Kelvin. By employing the best empirical interaction between each pair of particles, we solved the Schrödinger equation for the triatomic systems using hyperspherical coordinates in the adiabatic approximation. We found no bound states for 4H...

We present several pieces of evidence for strong-weak coupling duality symmetry in the heterotic string theory, compactified on a six dimensional torus. These include symmetry of the 1) low energy effective action, 2) allowed spectrum of electric and magnetic charges in the theory, 3) allowed mass spectrum of particles saturating the Bogomol’nyi bound, and 4) Yukawa couplings between massless n...
