Exact bound state solutions of the Schrödinger equation for generalized noncentral potential are examined by means of the Nikiforov-Uvarov method. The wavefunctions and the corresponding energy eigenvalues of the system are obtained analytically. The results examined for the potential are compatible with those obtained by the other methods.

Several realistic phenomenological nucleon-nucleon interaction models are employed to investigate the possibility of bound deuteron-like states of such heavy flavor hyperons and nucleons, for which the interaction between the light flavor quark components is expected to be the most significant interaction. The results indicate that deuteron-like bound states are likely to form between nucleons ...

We study the interaction of the Θ + pentaquark with nuclear matter associated to the KN decay channels and to the two meson cloud. We find that the potential is attractive and could be strong enough to lead to the existence of Θ + nuclear bound states.

The main features of nuclear reactions with participation of baryon resonances (∆(1232), S(1535) and Λ(1405)), which are interpreted as a manifestation of the bound states of nucleus and corresponding meson

OF THE DISSERTATION Energy-resolved positron-molecule annihilation: Vibrational Feshbach resonances and bound states

The QCD β-function and the anomalous dimensions for the Coulomb potential and the static potential first differ at three loop order. We evaluate the three loop ultrasoft anomalous dimension for the Coulomb potential and give the complete three loop running. Using this result, we calculate the leading logarithmic Lamb shift for a heavy quark-antiquark bound state, which includes all contribution...

We review ideas and speculations concerning possible bound states or resonances of the nucleon–antinucleon system.

We study D-brane bound states with a non-Abelian background on noncommutative T. We construct twisted quantum bundles and adjoint sections describing D-brane bound states. It is shown that the noncommutative T with non-Abelian backgrounds also exhibits SO(4, 4|Z) duality and the action of this group gives Morita equivalent T on which only D0-branes exist. For a reducible non-Abelian background,...

The one-dimensional Schrr odinger equation is considered when the potential and its rst moment are absolutely integrable. The potential is uniquely constructed in terms of the scattering data consisting of the reeection coeecient from the right (left) and the knowledge of the potential on the right (left) half line of the real axis. Hence, neither the bound state energies nor the bound state no...

Recently, an exact Green’s function of the diffusion equation for a pair of spherical interacting particles in two dimensions subject to a backreaction boundary condition was derived. Here, we use the obtained Green’s function to calculate exact expressions for the survival probability, the time-dependent reaction rate coefficient for the initially unbound pair and the survival probability of t...
