چکیده

We discuss the latest CCFR determination of the strange sea density of the proton. We comment on the differences with a previous, leading–order, result and point out the relevance of quark mass effects and current non–conservation effects. By taking them into account it is possible to solve the residual discrepancy with another determination of the strange quark distribution. Two important sources of uncertainties are also analyzed.

We examine the indirect effects of new physics on a variety of processes in the B system, such as the Z → b ¯ b vertex, the decays B → X s γ and B → X s ℓ + ℓ − , and CP violation.

We show that the all order summation of small x logarithms cannot be included in the Q evolution of structure functions because the NLLx corrections overwhelm the LLx contribution.
