Physics

Ok, now it is public, so I can also broadcast it: LHC last night got the two proton beams to collide at 2.36 TeV total center of mass energy. You can see a few event displays here: http://atlas.web.…

Well, as you know I cannot say anything about internal matters of the CMS experiment at the LHC, but I know that other sites will have information pretty soon on the matter. So my advice for tonight…

One of the cool things I have learned to do, through years of experience in data analysis at particle colliders, is to visualize the complex kinematics of a signal process in a multi-dimensional…

The verdict is out: Amanda Knox and Raffaele Sollecito killed Meredith Kercher. The murder of the young British student in Perugia two years ago was a highly disputed case, and the proof of guilt of…

I do not know about you, but top quarks fascinate me. Since my early years as a student in particle physics I participated in the top search, and then the top discovery, with the CDF experiment at…

The Carnival of Physics is an event organized by Gravità Zero and Gravedad Cero, two sites of scientific outreach in Italy and Spain. I participate with three recent articles which are published on…

Last night the Large Hadron Collider at CERN has circulated the highest-energy beams of particles ever produced. The beam energy has been brought up from the injection energy of 450 GeV to 1.18 TeV,…

I had an idea that the theories of the earliest stages of the universe were speculative.  I just never really knew how speculative until I really looked at them.  The CMB is as…

Can a subject be too remote from the domain of traditional physics for physicists to dare applying their methods of research to it? Unlikely. If the objects under investigation in some remote area of…
