The Phenomenology of Enhanced b → sg
Alexander L. Kagan · 1998
Potential hints for New Physics enhanced b -> sg dipole operators are reviewed. Implications for inclusive kaon spectra, and corrresponding search strategies are discussed. Remarkably, all B meson rare decay constraints can be evaded. Large CP asymmetries are expected if new contributions to the dipole operators contain non-trivial weak phases. A critical comparison of eta' production in the Standard Model and in models with enhanced b -> sg is presented. A Standard Model explanation of the large B -> eta' Xs rate measured by CLEO poses a challenge, evidently requiring novel non-perturbative order of magnitude enhancement of gluon anomaly mediated contributions. However, in the case of enhanced b -> sg the existence of a cocktail solution is very likely.
