...waiting for a piece I will post tomorrow, to stimulate your curiosity -and allow me to travel from Venice to Patras by ship, with no internet connection.
The subject is not only the Higgs mass, but the top quark mass. Which top mass ? The "pole" mass -the real part of the pole in the perturbative top-quark propagator. Have I lost you ? Ok, do not worry -definitions are for theorists. Let us just say that the top quark, being a complicated coloured object which thus cannot live free of the influence of strong interactions,
is measurable at a hadron collider like the Tevatron only within uncertainties of the order of a constant called "Lambda QCD", which is of the order of 200 MeV.
Beppe Grillo, one of the most successful bloggers in the world (last time I checked his blog
was number 11 in the world by traffic) descends in Italy's confusing political arena.
A new public document
has been made available on the CMS public web page yesterday morning. It reports on a study of the reach of the CMS detector, with data collectable in 2010, for a signal of large extra dimensions, using the very distinctive signature of a high-energy jet recoiling against -well, recoiling against nothing; or better, something which left our world and entered into another dimension of space.
From August 30th to September 2nd I will attend the 29th edition of "Physics in Collision" in Kobe, Japan, to hear a few interesting talks and to present a poster on behalf of CMS, about the search for the Standard Model Higgs boson.
Posters are what they sound like -big, illustrated sheets of paper. Many conferences have a "poster session" in which authors of the posters stand in front of their creation and discuss the details with colleagues and answer questions about the contents. Before the poster session, each poster is usually presented by the author with a short oral memo -five minutes each at PIC.
Sometimes playing online chess gives me some satisfactions. I only play 5-minute chess, but five minutes (times two, five for each player) are a looong time, during which adrenalin flows free in my veins. Chess is a drug: these 5-minute games are addictive, exhilarating, and damaging to one's ego at times. But when things go the right way, it really feels good.
Today I was paired with a Mongolian international master, IM Myagmarsuren, by the automatic pairing system of 5-minute blitz games on the ICC. Here is the game, with minimal commentary.

is an online repository of scientific papers in physics, astronomy, maths, cosmology, computer science, and a few other topics, where papers due to be published on scientific journals are submitted by the authors, and become quickly accessible for free to anybody before the peer-review process ran by the journals is over and they get printed there.
