A new analysis by the ATLAS collaboration, based of the data collected in 13 TeV proton-proton collisions delivered by the LHC in 2016, finds an excess of X-->4 lepton events at a mass of 240 GeV, with a local significance of 3.6 standard deviations. The search, which targeted objects of similar phenomenology to the 125 GeV Higgs boson discovered in 2012, is published in ATLAS CONF-2017-058. Besides the 240 GeV excess, another one at 700 GeV is found, with the same statistical significance.

This is the second part of a section taken from Chapter 3 of the book "Anomaly! Collider Physics and the Quest for New Phenomena at Fermilab". The chapter recounts the pioneering measurement of the Z mass by the CDF detector, and the competition with SLAC during the summer of 1989. The title of the post is the same as the one of chapter 3, and it refers to the way some SLAC physicists called their Fermilab colleagues, whose hadron collider was to their eyes obviously inferior to the electron-positron linear collider.

Last week-end Padova researchers tested the first calorimeter and tracker prototypes of the iMPACT project at the APSS/TIFPA Proton Therapy Facility in Trento (Italy).

iMPACT (innovative Medical Proton Achromatic Calorimeter and Tracker) is a project led by Piero Giubilato, who won an ERC consolidator grant from the European Union. The project aims to develop a high resolution and high rate (>100 kHz/cm2) proton Computed Tomography (pCT) scanner. The scanner will combine a highly-segmented range calorimeter made of PVT scintillators, for energy measurements, and a silicon pixel tracker, for trajectory reconstructions. 

The clip below, together with the following few which will be published every few days in the coming weeks, is extracted from the third chapter of my book "Anomaly! Collider Physics and the Quest for New Phenomena at Fermilab". It recounts the pioneering measurement of the Z mass by the CDF detector, and the competition with SLAC during the summer of 1989.

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.
