A new long article which appeared on the arXiv preprint repository last week is sending ripples around the world of particle physics phenomenology, as its main result -if proven correct- will…

Tomorrow morning the Cornell arXiv will publish the preprint of a long scientific article, the result of 4.5 months of painstaking work by yours truly. So I thought I would give you a preview of its…

Waves of geometry in four-dimensional space-time, that is what gravitational waves are.  The very definition of distance between points in space-time changes as these waves pass.   The…

A few days ago I received from my esteemed colleague Massimo Passera, a theorist and an INFN director of research in the Padova section where I also work, a draft of a new article he produced with…

The Tevatron collider, the giant marvel accelerator built at the Fermi National Accelerator Laboratory in the eighties and operated there for over thirty years, until its demise in 2012, lost one of…

The ATLAS Collaboration has released last week the results of a careful analysis of a large dataset of proton-proton collisions acquired during Run 2 of the Large Hadron Collider. This is a…

One of the most suprising results of the "Machine Learning for Jets" (but really, for particle physics in general) workshop I attended in New York City two weeks ago was the outcome of a challenge…

The third "Machine Learning for Jets" workshop is ongoing these days at the Kimmel centre of New York University, a nice venue overlooking Washington Square park in downtown Manhattan. I came to…

Majorana fermions, particles that act as their own antiparticle and were first hypothesized by Italian physicist Ettore Majorana in 1937, have not been detected after all. A 2017 report of the…

There is dark energy as sure as there is light in the world. It just may not be a simple scalar multiplier in our equations as we had hoped it would be. Dark energy is what the scientific consensus…
