Cavendish – HEP – 99 / 02 DAMTP – 1999 – 44 hep - ph / 9904244 Jet Rates at Small x to Single - Logarithmic

We present predictions of jet rates in deep inelastic scattering at small x to leading-logarithmic order in x, including all sub-leading logarithms of Q/μ R where μR is the transverse momentum scale at which jets are resolved. We give explicit results for up to three jets, and a perturbative expansion for multi-jet rates and jet multiplicities.

We discuss how momentum conservation is implemented in perturbative computations based on expansions of anomalous dimensions appropriate at small x. We show that for any given choice of F 2 coefficient functions there always exists a factorization scheme where the gluon is defined in such a way that momentum is conserved at next to leading order.

Vacuum Oscillation Solution to the Solar Neutrino Problem

The vacuum oscillation (VO) solution to the solar anomaly requires an extremely small neutrino mass splitting, ∆m2sol < ∼ 10 −10 eV. We study under which circumstances this small splitting (whatever its origin) is or is not spoiled by radiative corrections. The results depend dramatically on the type of neutrino spectrum. If m21 ∼ m22 > ∼ m23, radiative corrections always induce too large mass ...
