Sorry to have been quite for a while: I was too busy having a quiet time!
For two whole weeks, I did not budge from CERN, and so was able to catch up on a couple of projects. One of these was a fresh look at the constraint on supersymmetry imposed by the rare B_s to mu mu decay. The CDF and D0 experiments at Fermilab have been looking for this: no banana so far, but they have good prospects to improve significantly their sensitivity, and subsequently the CMS and ATLAS experiments should be able to push much further, and observe this decay at the level expected in the Standard Model. New physics accessible to the LHC, such as supersymmetry, might make B_s to mu mu decay less rare than in the Standard Model. Unfortunately, as Keith Olive, Vassilis Spanos and I pointed out in https://arxiv.org/abs/hep-ph/0504196, calculating the rate for B_s to mu mu decay is complicated by uncertainties in Standard Model parameters such as the masses of the top and bottom quarks, clouding the interpretation of this prospective constraint on supersymmetry.
I was also able to write up the talk I gave a few weeks ago in Kolkata on `From Little Bangs to the Big Bang', an introductory review of aspects of the connection between particle physics and cosmology that I hope you might find interesting: https://arxiv.org/abs/astro-ph/0504501.
Not travelling does not mean that I have been neglecting my other job looking after CERN's external relations! I met a delegation from Romania, participated in a diplomatic reception for ambassadors to international organizations in Geneva and gave an introductory presentation of CERN to a group of visitors from the UK. I also dealt with aspects of CERN's relations with Argentina, Chile, Cyprus, India and Ireland. I also worked to bring some undergraduate students from non-member countries to participate in our summer intern programme, and prepared an application to the European Union for a project to support PhD students to work for periods in the CERN Theoretical Physics Division.
I also spent some time thinking about CERN's possible future projects such as CLIC - for a recent progress report by Ian Wilson, see: https://clic-meeting.web.cern.ch/clic-meeting/, and attended an inspirational seminar by Peter McIntyre about high-field magnets and the possibility of tripling the LHC energy some day.
Oof! After all that, the following week of travel almost comes as a relief ....
