Confining the electroweak model to a brane
Abstract
We introduce a simple scenario where, by starting with a fivedimensional SU(3) gauge theory, we end up with several 4D parallel branes with localized fermions and gauge fields. Similar to the split fermion scenario, the confinement of fermions is generated by the nontrivial topological solution of a SU(3) scalar field. The 4D fermions are found to be chiral, and to have interesting properties coming from their 5D group representation structure. The gauge fields, on the other hand, are localized by loop corrections taking place at the branes produced by the fermions. We show that these two confining mechanisms can be put together to reproduce the basic structure of the electroweak model for both leptons and quarks. A few important results are: Gauge and Higgs fields are unified at the 5D level; and new fields are predicted: One lefthanded neutrino with zerohypercharge, and one massive vector field coupling together the new neutrino with other lefthanded leptons. The hierarchy problem is also addressed.

A brane scenario is envisaged in which the mdimensional bulk is endowed with a GaussBonnet term and localization of matter on the brane is achieved by means of a confining potential. The resulting Friedmann equations on the brane are modified by various extra terms that may be interpreted as the Xmatter, providing a possible phenomenological explanation for the accelerated expansion of the Universe. The age of the Universe in this scenario is studied and shown to be consistent with the present observational data.

Braneworld black hole solutions via a confining potential
Using a confining potential, we consider spherically symmetric vacuum (static black hole) solutions in a braneworld scenario. Working with a constant curvature bulk, two interesting cases/solutions are studied. A Schwarzschildde Sitter black hole solution similar to the standard solution in the presence of a cosmological constant is obtained which confirms the idea that an extra term in the field equations on the brane can play the role of a positive cosmological constant and may be used to account for the accelerated expansion of the universe. The other solution is one in which we can have a proper potential to explainmore » 
Multichannel scattering with nonlocal and confining potentials. II. Application to a nonrelativistic quark model of the NN interaction
The generalized Levinson theorem for systems involving nonlocal and confining potentials is illustrated by a nonrelativistic quark model for the {ital NN} interaction, formulated within the framework of the resonating group (RG) method. In order to apply the results of the preceding paper to this problem, we first show how the system of integrodifferential equations of the RG method can be transformed into a system of coupled Schroedinger equations with nonlocal potentials. The forbidden states arising in the manychannel wave function from the Pauli principle are then shown to play the same role as normalizable bound states, as far asmore » 
Heavy mesons in a simple quarkconfining twostep potential model
We study the mass spectra and decay widths of UPSILON resonances in a simple quarkconfining, analytically solvable, twostep potential model used earlier to study the charmonium system and even the light mesons such as ..pi.., rho, K,... Results are found to be in good agreement with experiments and also with the values predicted by others. We predict the BBbar threshold at 10.242 GeV, which means in our model the first three radial UPSILON excitations UPSILON(9.4345), UPSILON'(9.9930), and UPSILON''(10.1988) are stable with respect to the Zweigruleallowed decay UPSILON..>..BBbar. The mass spectrum and thresholds of the anticipated ttbar states are also studiedmore » 
Exactly solvable wave equation with a linear confining potential I. Asymmetric model
A wave equation is presented which describes the confinement of a Dirac particle by means of a static linear potential. The model is exactly solvable and all solutions are tabulated. Also a complete set of commuting observables is given which can be used to characterize these solutions uniquely. The eigenvalues for the total angular momentum, j, and the energy squared, E/sup 2/, arrange themselves into linear and parallel Regge trajectories. Finally, a discussion is given of the highmass limit.
