S to P wave form factors in semi-leptonic B decays
S. Veseli, M. G. Olsson
We apply HQET to semi-leptonic and meson decays into the observed charmed wave states. In order to examine the sensitivity of the results to the choice of a specifi…
Radiative rare decays revisited
S. Veseli, M. G. Olsson
We reexamine contributions of higher -resonances to the radiative rare decays $b\rar sγ$ in the limit where both - and -quark are considered heavy. Using the non-relativis…
Flux Tubes in Effective Field Theory
M. G. Olsson, S. Veseli, K. Williams
Quark-antiquark bound states are examined in the long-range strong-coupling limit with the minimal area law of lattice gauge theory assumed as input. Matrix element relations are e…
On the instantaneous Bethe-Salpeter equation
M. G. Olsson, S. Veseli, K. Williams
We present a systematic algebraic and numerical investigation of the instantaneous Bethe-Salpeter equation. Emphasis is placed on confining interaction kernels of the Lorentz scala…
Fermion Confinement by a Relativistic Flux Tube
M. G. Olsson, S. Veseli, K. Williams
We formulate the description of the dynamic confinement of a single fermion by a flux tube. The range of applicability of this model extends from the relativistic corrections of a…
