We report scattering lengths for the Sg 1 , Su 1 , and Sg 1 adiabatic molecular potentials relevant to collisions of two metastable 2 S helium atoms as a function of the uncertainty in theseâ€¦ (More)

We report results for the Lorentzian profiles of the Li I, Na I and K I doublets and the Na I subordinate doublet broadened by helium perturbers for temperatures up to 3000 K. They have been obtainedâ€¦ (More)

We report scattering lengths for the 1 Î£ + g , 3 Î£ + u and 5 Î£ + g adiabatic molecular potentials relevant to collisions of two metastable 2 3 S helium atoms as a function of the uncertainty in theseâ€¦ (More)

Collisions between tightly confined atoms can lead to ionization and hence to loss of atoms from the trap. We develop second-order perturbation theory for a tensorial perturbation of a sphericallyâ€¦ (More)

Gluon mediated exclusive hadronic decays of b quarks are studied within the standard model (SM) and the constrained minimally supersymmetric standard model (MSSM). For all allowed regions of the MSSMâ€¦ (More)

The bound states of the fermionic (3)He(2 (3)S(1)) + (3)He(2 (3)P(j)) system, where j = 0, 1, 2, are investigated using the recently available ab initio short-range (1,3,5)Î£(+)(g,u) and (1,3,5)Î (g,u)â€¦ (More)

We analyse the electric dipole moment of the neutron in the MSSM, induced by the renormalisation of the soft-susy breaking terms. We run the RGEs using twoloop expressions for gauge and Yukawaâ€¦ (More)

Abstract In this paper we extend the results of previous work on spontaneous baryogenesis to general models involving CP violation in the Higgs sector. We show how to deal with Chern-Simons termsâ€¦ (More)

Gluon mediated exclusive hadronic decays of b quarks are studied within the standard model ~SM! and the constrained minimally supersymmetric standard model ~MSSM!. For all allowed regions of the MSSMâ€¦ (More)

Recent theoretical investigations [M. Beneke et al. Phys. Rev. Lett. 83, 1914 (1999)] of two-body hadronic B decays have provided justification, at least to order Î±s, for the use of the factorizationâ€¦ (More)
