چکیده
We rewrite the 1+1 Dirac equation in light cone coordinates in two significant forms, and solve them exactly using the classical calculus of finite differences. The complex form yields “Feynman’s Checkerboard”—a weighted sum over lattice paths. The rational, real form can also be interpreted in terms of bit-strings. Submitted to Physics Letters A.

Fermion compositeness and other new physics can be signalled by the presence of a strong four-fermion contact interaction. Here we present a study of llqq and llll contact interactions using the reactions: ll → ll, bb̄, cc̄ at future ee linear colliders with √s = 0.5− 5 TeV and μμ colliders with √ s = 0.5, 4 TeV. We find that very large compositeness scales can be probed at these machines and tha...

A quantisation of chiral symmetry within the Skyrme crystal is carried out. The definition of global isospin in the crystal is explored, and found to be ambiguous. However, the state corresponding to a neutron crystal is identified, and the leading quantum correction to the classical mass is computed. The results are compared to those of Klebanov for a crystal of whole skyrmions.

SO(10) grand unified models have an intermediate symmetry group in between SO(10) and SU (3) C ⊗ SU (2) L ⊗ U (1) Y. Hence they lead to a prediction for proton lifetime in agreement with the experimental lower limit. This paper reviews the recent work on the tree-level potential and the one-loop effective potential for such models, with application to inflationary cosmology. The open problems a...

We calculate the Green function for the Dirac equation describing a spin 1/2 particle in the presence of a potential which is a sum of the Coulomb potential VC = −A1/r and a Lorentz scalar Vs = −A2/r. The bound state spectrum is obtained. PACS numbers:03.65.Pm,03.65.Ge ⋆ e-mail:[email protected]

We examine the indirect effects of new physics on a variety of processes in the B system, such as the Z → b ¯ b vertex, the decays B → X s γ and B → X s ℓ + ℓ − , and CP violation.
