Muon G-2: The Anomaly That Could Change Physics

by Tommaso Dorigo

Do you remember the infamous “g-2” measurement ? The anomalous magnetic moment of the muon has been for over a decade in the agenda of HEP physicists, both as a puzzle and as a hope for good things to come.

Ever since the Brookhaven laboratories estimated the quantity at a value over 3 standard deviations away from the equally precise theoretical predictions, the topic (could the discrepancy be due to new physics??) has been commonplace in dinner table conversations among HEP physicists.

Similarly, no self-respected “global fit” of standard model observable quantities or scan of allowed parameter space of supersymmetric theories Continue reading “Muon G-2: The Anomaly That Could Change Physics”

SciComm in Erice

by Giles Strong

Last week I, along with fellow network ESR Pablo, attended the International School of Science Journalism in Erice, on the Italian island of Sicily. As regular readers of this blog will know, scientific outreach plays an important role in our network activities, and I’d attended with the hope of gaining tips for better simplifying and presenting my research. Continue reading “SciComm in Erice”

Invitation to Astro@Stats 2017

by the AMVA4NewPhysics press office

On September 8, 2017 the Department of Statistical Sciences of the University of Padova will host Astro@Stats 2017, a Sino-Italian Workshop on Astrostatistics. Continue reading “Invitation to Astro@Stats 2017”

My impressions on the RooStats Tutorial

by Greg Kotkowski

On the 19th of May I was very glad to take part in the RooStats tutorial organised by the AMVA4NewPhysics Network as a part of a workshop in Oviedo. RooStats is a ROOT library that uses the “RooFit” package, and provides classes to perform statistical analysis. The tutorial was attended by all the ESR from our Network, among which I was the only non-physicist. I am a statistician who does not use ROOT at all. For this reason, my attendance at the tutorial could seem Continue reading “My impressions on the RooStats Tutorial”

GSI

by Tommaso Dorigo

GSI, the Helmholtz Centre for Heavy Ion Research, is a laboratory located near the town of Darmstadt, in central Germany, just a few miles away from the Frankfurt airport. The centre was founded in 1969, and has since then been a very active facility where heavy elements are studied (six rare heavy ones were in fact discovered there, including the one they named Darmstadtium!), and where Continue reading “GSI”

W Mass: Closing In

by Tommaso Dorigo

After a lot of agonizing work on tiny systematic uncertainties, the ATLAS collaboration released in time for the Moriond conference their latest measurement of the W boson mass (in fact the only one so far). The result is in close match with previous determinations, and has a slightly larger error bar than those. So why bother discussing it here ?

There is a reason. The W boson is one of the most important subatomic particles Continue reading “W Mass: Closing In”

AMVA4NewPhysics Deliverable 4.1: Report of the Performance of Algorithms for Data-Driven Background Shape Modeling

by AMVA4NewPhysics press office

And here it is, the second – but really synchronous in publication with the first – scientific deliverable of our network. Deliverable 4.1, titled “Report of the Performance of Algorithms for Data-Driven Background Shape Modeling“, is a report of studies performed by network members operating within Work Package 4, also known as “New Statistical Learning Tools for HEP Analysis“.

The research presented in this document aims at constructing a precise representation of background processes to searches for small signals in hadron collider data. Specifically, we focused on the multijet QCD background, Continue reading “AMVA4NewPhysics Deliverable 4.1: Report of the Performance of Algorithms for Data-Driven Background Shape Modeling”

AMVA4NewPhysics Deliverable 1.1: MVA for Higgs Boson Searches at the LHC

by the AMVA4NP press office

It is with a certain satisfaction that I can announce today that the AMVA4NewPhysics network is in complete control of its planned schedule, and has now started to provide real research-grade output, delivering its first two scientific products of relevance. Deliverable 1.1 (from work package 1, which focuses on MVA applications to Higgs boson studies) and Deliverable 4.1 (from work package 4, which focuses on the development of entirely new Machine Learning tools with in mind their application to specific HEP Continue reading “AMVA4NewPhysics Deliverable 1.1: MVA for Higgs Boson Searches at the LHC”

Anomaly! Now Available As E-Book

by Tommaso Dorigo

Today I would like to mention that my book “Anomaly! Collider Physics and the Quest for New Phenomena at Fermilab” is now available for purchase as E-Book at its World Scientific site.
For the occasional readers and the absent-minded regulars, below I paste a summary of what the book is about, the endorsements it received from distinguished scientists in the field, and a few links to reviews in internet resources. The web site of the book at World Scientific is here. At the WS site you Continue reading “Anomaly! Now Available As E-Book”
