“…In the 1970's and 80's, there were several comparisons of electron and muon scattering [6,7] which supported universality of the interaction at the 10% level, but none were precise enough to reveal proton radius issues. The radius of 12 C was determined in electron scattering and in muonic carbon atoms and the results agreed within the error bars of the measurements at that time.…”

Abstract. The proton radius puzzle is the difference between the proton radius as measured with electron scattering and in the excitation spectrum of atomic hydrogen, and that measured with muonic hydrogen spectroscopy. The MUSE experiment seeks to resolve this puzzle by simultaneously measuring elastic electron and muon scattering on the proton, in both charge states, thereby providing new information to the puzzle. MUSE addresses issues of two-photon effects, lepton universality and, possibly, new physics, while providing simultaneous form factor, and therefore radius, measurements with both muons and electrons.

“…This brought back good memories to me because I had worked on the second g − 2 experiment when I was a postdoc at CERN in 1965-66 [28]; but, of course, Prof. Zichichi worked on the ground-breaking original g − 2 experiment at CERN in 1959-1961 [29]. My thesis research, done at the BNL-AGS from 1961-64, was muon-proton elastic scattering [30] to find out "Why does the muon weigh heavy?" Even in 2013, with Prof. Higgs in the audience, we still don't know!…”

Highlights from Brookhaven National Laboratory (BNL) and experiments at the BNL Relativistic Heavy Ion Collider (RHIC) are presented for the years 2011-2013. This review is a combination of lectures which discussed the latest results each year at a three year celebration of the 50th anniversary of the International School of Subnuclear Physics in Erice, Sicily, Italy. Since the first collisions in the year 2000, RHIC has provided nucleus-nucleus and polarized proton-proton collisions over a range of nucleon-nucleon c.m. energies ( √ s N N ) from 7.7 to 510GeV with nuclei from deuterium to uranium, most often gold. The objective was the discovery of the Quark Gluon Plasma, which was achieved, and the measurement of its properties, which were much different than expected, namely a 'perfect fluid' of quarks and gluons with their color charges exposed rather than a gas. Topics including quenching of light and heavy quarks at large transverse momentum, thermal photons, search for a QCD critical point as well as measurements of collective flow, two-particle correlations and J/Ψ suppression are presented. During this period, results from the first and subsequent heavy ion measurements at the Large Hadron Collider (LHC) at CERN became available. These confirmed and extended the RHIC discoveries and have led to ideas for new and improved measurements.

“…However, the muonic hydrogen measurements yield a radius of ≈0.84 fm. Measurements of µ p scattering date back to the 1970s-80s [9,10], and are not precise enough nor low enough in Q 2 to have a clear impact. A recent summary of proton radius extractions is shown in Fig.…”
