Physics

On today's online version of the highest-diffusion newspaper in Italy, Il Corriere Della Sera (a bit too right-winged for me, but still an important source) stands a piece signed by none less than Carlo Rubbia, Physics Nobel prize in 1984 for the discovery of W and Z bosons. Despite his not so young age any more, Carlo is still extremely active in the field of high-energy physics, where he has moved his interest into neutrino physics.

Time and space are joined at the hip. I mean this in a completely naked, having an amazing animal experience together kind of way. A review of the history of physics will support this scandalous claim.

It has been a while since I last wrote about results from the DZERO collaboration, and I am happy to be given a chance to do so by my casual Monday morning browsing of the most recent Arxiv preprints.
"The observed exclusion limit is found from the point where the 95% quantile (dotted
line) crosses the median value of the distribution of Q values for the QCD prediction
(dashed line). This occurs at Lambda = 9.5 TeV. The expected limit is Lambda = 5.7 TeV. [...]
As a cross-check, a Bayesian analysis of F(mjj) has been performed, [...]. This analysis sets a 95% credibility level of Lambda > 6.7 TeV. The expected limit from this Bayesian analysis is 5.7 TeV, comparable to the CLs+b expected limit. While the observed limit from CLs+b analysis is significantly higher than the Bayesian results, we have no basis on which to exclude the CLs+b result a posteriori."
This might become the title of a series of posts, much like my "say of the week" series. In fact, the Large Hadron Collider is back in operation since earlier this month, and the instantaneous luminosity at which it collides protons at a center-of-mass energy of 7 TeV is going to keep gradually increasing, as better orbit parameters are found, more protons are injected in the machine, more bunches are made to circulate, and beams are squeezed in the surroundings of the experimental halls.

Still, it feels nice to report that the value of L = 2.4E32 cm^-2 s^-1 has been now achieved, a full 20% more than the highest number recorded in the 2010 running.
Lacking the papers to prove I am a theoretical physicist, I have built something working class: a lunchbox

The box contains Yoplait Yogurt, Del Monte 100 Calorie Mixed Fruit, and White Cheddar Cheese Smart Food Pop Corn (note: all product placements are unpaid). The apple included indicates I work on gravity.

The CDF collaboration sent to the preprint arxiv a new paper a few days ago. In it, they report on a measurement of the mass difference of top and anti-top quarks. The result would not be worth discussing in detail, if it did not show a 2-sigma discrepancy which might be the first hint of a CPT violation. So let me discuss it here.
My blogging output here is scarce this week, because I am spending my time at the NEUTEL 2011 conference in Venice. I am producing some posts summarizing the talks I hear at the conference, together with a few colleagues. Our blog there will be short-lived, but already collects about 1000 views a day, growing by the day. Here is a selection of recent posts you can find -I only list here those published today or yesterday:

99942Apophis A asteroid which if it were to hit earth would hit off the coast of California and do damage similar to the Earthquake. A 9.0 magnitude earthquake is equal to about 450 megatons of TNT being set off underground.  Due to the situation at the Daiichi nuclear plant near in Sendai Japan there is much talk of how nuclear plants should not be built in earthquake zones.
What is a BLEVE?

A BLEVE is a Boiling-Liquid Expanding-Vapor Explosion.

It is fairly common knowledge that removing the radiator cap of a vehicle with a hot engine will cause the ejection of boiling water.
