This is just to report that I feel greatly honoured to be cited on top of the acknowledgements section of the new paper by Dimitri Nanopoulos and colleagues.

I hope I will be able to review the paper for you here soon. The title ("Primordial Synthesis: F-SU(5) SUSY Multijets, 140-150 GeV LSP, Proton and Rare Decays, 125 GeV Higgs Boson, and WMAP7") promises a lot...

Below is a clip of the "acknowledgement" of my contribution (just a very pleasant chat with Dimitri in Athens last August, and little more).

CMS Vs ATLAS On Dijet Resonances: Who Wins ?

Oct 11 2012 | comment(s)

Two papers describing results of searches for high-mass resonances decaying into jet pairs have appeared on the arxiv this week. They are authored by the CMS and ATLAS collaborations, and they both report lower limits on the mass of hypothetical particles predicted by several new physics signatures. Both collaborations base their results on the analysis of their full 2011 datasets.

Five years ago I was fascinated by an analogy used by my friend Michelangelo Mangano to explain the problem of naturalness, a crucial issue in fundamental physics, and maybe the biggest single indicium we have that new physics beyond the standard model of particle physics should exist, and be not too far away from our current experimental reach.

Significance In Presence Of Systematics, And The LHCb Observation Of Bs Decays To Pion Pairs

In particle physics searches (and elsewhere) the word "significance" is associated with the quantitative measure of how discrepant is one observation with a so-called "null hypothesis". That is, one searches for a new effect in some dataset, and defines what one expects to see in the absence of anything discrepant from theoretical predictions: that is the null hypothesis. A new particle in the data will usually manifest itself as an excess of events, and this will cause the data to deviate from expectations.

As my twenty three affectionate readers will probably remember, I enjoyed a very pleasant week in Kolymbari (Crete) last June, attending the first International Conference of Frontier Physics. Now, after you attend a conference and give there a presentation, you are supposed to produce a writeup of your talk for the proceedings book. So while October arrives unannounced with critically important errands to attend to, I find myself in the need to produce a 12-page document describing the most recent and important results of the CMS experiment.
