In memoriam of Federico Casagrande
I had the chance to meet Federico in a series of conferences organized by Rodolfo Bonifacio of University of Milan at Gargnano on Garda Lake. The last time I met him was on September 2003 at this conference. Federico was an associate professor at University of Milan, an expert in quantum optics, and it was [...]
A Millenium Problem issue
As my readers know, a recurring question in this blog is the solution to the Millenium Problem on Yang-Mills theory. So far, we have heard no fuzz about this matter and the page at the Clay Institute is no more updated since 2004. But in these years, activity on this problem has been significant and [...]
From arxiv today
Today the daily from arxiv is particularly rich. A couple of papers are from my friend Marco Ruggieri, one in collaboration with Raul Gatto (see here) and the other is the contribution to Paris Conference proceedings (see here). Marco is currently using a Nambu-Jona-Lasinio model to understand the behavior of hadronic matter at high temperatures [...]
QCD is confining
At Bari Conference, after I gave my talk, Owe Philipsen asked to me about confinement in my approach. The question came out also in the evening, drinking a beer at a pub in the old Bari. Looking at my propagator, it is not so straightforward to see if the theory is confining or not. [...]
The Gauge Connection is on Facebook!
Starting from to today, I opened a site for the blog on Facebook (see here). Feel free to comment or add something interesting for our lines of research. Filed under: Facebook, Physics

A box seat at OPERA
While at Bari Conference (see here), the news was spreading that OPERA Collaboration, a long baseline experiment using muon neutrino beams launched by CERN by CNGS Project, detected a possible Lorentz violating effect. Initially, it started as a rumor in the comment area at Jester’s blog (see here). Then, Tommaso Dorigo provided a full account [...]
The XV Workshop on Statistical Mechanics and nonperturbative Field Theory
This week I was in Bari as the physics department of that university organized a major event: SM&FT 2011. This is a biennial conference having the aims to discuss recent achievements in fields as statistical mechanics and quantum field theory that have a lot of commonalities. The organizers are well-known physicists and so it was [...]
An interesting review
It is some time I am not writing posts but the good reason is that I was in Leipzig to IRS 2011 Conference, a very interesting event in a beautiful city. It was inspiring to be in the city where Bach spent a great part of his life. Back to home, I checked as usual [...]
Higgs particle heavier than ever?
Today in Mumbai (India), at the Lepton-Photon 2011 Conference, talks announcing new results from LHC were held. Data taking claimed almost doubling of data since July Conference in Grenoble. The results were striking and somewhat unexpected. In order to have an idea you should read this CERN press release and the general mood of people [...]
It was twenty years ago today . . .
With these beautiful words starts a recollection paper by the founder of arXiv, Paul Ginsparg. This is worth the reading as this history spans a number of years exactly overlapping the computer revolution that definitely changed our lives. What Paul also changed through these new information tools was the way researchers should approach scientific communication. [...]
Soverato beach
It is some days that I am not posting here but there is a very good reason: I am on vacation at Satriano, very near Soverato. These are wonderful places in Italy, in the southern region of Calabria. For your pleasure I post here a couple of photos of the moon on the sea at [...]
What’s going on with Higgs particle?
The aftermath of the EPS Conference is quite exciting on a side. Higgs hunting points to an unexpected direction even if some residuals of an old expectation are still there. I just want to show you the graphs of this conference from Tevatron and LHC From these it is very clear that the excluded range [...]

EPS awards five Italian physicists!
These are exciting times, waiting for the big hit from LHC. Some glimpses of what is awaiting us are now discussed at the European Physical Society (EPS) Conference in Grenoble (see here) that today will close. In conjunction with the scientific program, EPS has awarded some physicists for their research achievements at this Conference (see [...]
Slowness in a quantum world
Some days are gone since my last post but for a very good reason. I was very busy on writing down a new paper of mine. Meanwhile, frantic activity was around in the blogosphere due to EPS Conference in Grenoble. No Higgs yet but we do not despair. Being away from these distractions, I was [...]
Galileo’s abjuration
In these days there is a great chance in Rome to take a look to an important part of Vatican Secret Archives. These archives span almost two thousand years of history with the most part of them being part of the build up of Western civilization. Vatican made available a hundred documents that are exposed [...]
Paper on critical temperature revised
Yesterday, I have uploaded a new version of my paper on the critical temperature of chiral symmetry breaking in QCD (see here). The reason for this was that there are some points in need for a better clarification. The main of these is the mapping theorem: I have added a sketch of a proof. The [...]
Evidence of a QCD critical endpoint at RHIC
A critical endpoint in QCD is a kind of holy grail in nuclear physics. It has been theorized as a point where deconfinement occurs and hadronic matter leaves place to some kind of plasma of quarks and gluons. We know that the breaking of chiral symmetry is something that people has proposed several years ago [...]
Back from Paris
It is several days that I have no more posted on the blog but for a very good reason: I was in Paris for the Eleventh Workshop on Non-Perturbative Quantum Chromodynamics (see here). It has been a beautiful chance to see Paris with the eyes of a tourist and being immersed in a lot of [...]
