- Lattice QCD Calculations Disprove Anomaly In Muon Gyromagnetic Ratio
-
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 completely wipe off the table the one and only long-standing inco ...

- The Virus That Turns Physicists Into Crackpots
-
First off, let me say I do not wish to sound disrespectful to anybody here, leave alone my colleagues, to most of which goes my full esteem and respect (yes, not all of them, doh). Yet, I feel compelled to write today about a sociological datum I have paid ...

- The Plot Thickens: Yet Another Lattice QCD Calculation Restores The Anomaly Of The Muon Magnetic Moment
-
In a recent post I discussed the conclusions of a study aimed at computing a small but very important correction to the theoretical prediction of the anomalous magnetic moment of the muon. The interest of this lays in the fact that the latter quantity is v ...

- Gemstone Classification With A Specific Gravity Scale
-
The isolation that most of the civilized world has been subjected to, during the past few weeks, has produced a number of nasty effects, first and foremost on our economies, but it has also had a few positive ones. One of them is, at least in my case, an u ...

- Nuisance Parameters In Classification Problems: A Simple Example
-
These days I have been writing a chapter of a book on machine learning for physics, and in so doing I have found myself pondering on how to best explain, in very simple terms, the nocuous effect that model uncertainty may have on the result of a classifica ...

- A Tribute To Teresa Rodrigo
-
I was very saddened the other day upon learning from a colleague that Teresa Rodrigo Anoro passed away. Teresa was a professor at IFCA, University of Cantabria in Santander, Spain, where she held the position since 1995. At the IFCA she led a strong team o ...

- Who Discovered The Top Quark Anyway?
-
You may be wondering, upon reading the above title of this post, what I am after today: the top quark has been around for 25 years now, and there is no long-standing controversy on who discovered it-almost. Well, I will come to that in due time, but to exp ...

- Anomaly!: The Lost Chapters (Part 1)
-
When I wrote the final version of the book "Anomaly! Collider physics and the quest for new phenomena at Fermilab", four years ago, I had to get rid of a lot of material which would not fit within the strict page limit requested by my prospective ...
