Branching Ratios and CP Asymmetries of B Decays to a Vector and a Pseudoscalar Meson
N. G. Deshpande, B. Dutta, Sechul Oh
We consider two body decays of B meson into a light vector (V) and a pseudoscalar (P) meson. The constraint obtained from the modes on the parameter space of the input p…
Multilepton signatures of gauge mediated SUSY breaking at LEPII
Kingman Cheung, Duane A. Dicus, B. Dutta +1
In the framework of gauge-mediated supersymmetry breaking models pair production of the lightest neutralinos, scalar leptons, or charginos at LEPII gives rise to interesting signal…
Effective QCD coupling and power corrections to photon-photon scattering
F. Hautmann
The scattering of two off-shell photons is an infrared-safe process in QCD. For photon virtualities in the range of a few GeV, accessible at LEPII, power-behaved contributions to t…
A Critical Study of B Decays to Light Pseudoscalar
N. G. Deshpande, B. Dutta, Sechul Oh
Motivated by the large branching ratios observed for the process , we examine critically all the ingredients that go into estimates of B decays into two light pseu…
BFKL Scattering at LEPII and a Next e+ e- Collider
S. J. Brodsky, F. Hautmann, D. E. Soper
We discuss virtual photon scattering in the region dominated by BFKL exchange and report results for the cross sections at present and future e+ e- colliders.
Diffraction in DIS and Elsewhere
Davison E. Soper
I review some of the results presented in the working group on diffraction at DIS97, with a particular emphasis on the theory of diffractive hard scattering.
