The INFN School Of Statistics In Vietri, 2013

Statistics data analysis is one of those things that experimental physicists learn along the way. It is not a topic usually included in the curriculum studiorum of physics students at Universities: only few basic ingredients are taught during laboratory co ...

Uncommon Descent Uncommonly Decent On Relativistic Physics But What In God’s Name

Vincent J. Torley in “ Bad science by Dr. Victor Stenger, arguing in the cause of atheism ” argues well about quite difficult and controversial physics. ...

Some Blackboard Work

This morning I arrived to my office with one idea to develop, and I decided to work on the blackboard that is hung on the wall opposite to where I sit. I seldom use it, but for some reason it seems that writing with coloured markers on that white surface i ...

Comparison Of Multi-Variate Discriminants

The problem of classifying elements of a data set as belonging to one class or another, depending on their characteristics, is a very, very well-studied one, and one which is particularly important in particle physics. Imagine, for instance, that you colle ...

The Plot Of The Week- B Production Cross Section

LHCb, one of the two "satellite" experiments at the Large Hadron Collider, is a detector focusing on the production of B hadrons in proton-proton collisions. It does so by looking at only one side of the collision point, which is showered by the ...

Two 'Facts' in Modern Physics Courses that everyone learns but just ain't so...

I have had my fair share of confusion and straightening out over the years, mostly something I accept as a challenge (life wouldn't be fun without challenges...) But it struck me as strange when I finally found out that two things they taught me when ...

Finding Bosons Inside Jets

A thick paper by the ATLAS collaboration has been published by the Cornell Arxiv today. It is going to become a reference to all ATLAS analyses searching for new phenomena at high energy, or studies of boosted top quarks or vector bosons; and a good exampl ...

Those $1000 Said No New Physics At The TeV Scale... And They Did Not Lie

In September 2006 I was in Ponta Delgada, the main town of the island of San Miguel in the Azores, for a physics conference where I was presenting results of the CDF experiment. I remember listening to a very nice talk by Guido Martinelli, who was discussi ...

The muon collider: Possibly getting more particle physics bang, for less bucks, by accelerating more massive particles.

In short particles with more mass lead to beams with more energy.  More massive particles reach these energies with much smaller machines. Interesting and fundamental physics would be possible with a muon collider, of 6.3 km circumference and neutrino fac ...
