On mass and matter by Roberts, Craig D.

“…The visible Universe is largely characterised by a single mass scale, namely, the proton mass, m p . Contemporary theory suggests that m p emerges as a…”

Revealing the Origin of Mass through Studies of Hadron Spectra and Structure by Roberts, Craig D.

“…The Higgs boson is responsible for roughly 1% of the visible mass in the Universe. Obviously, therefore, Nature has another, very effective way of generating…”

Fresh Extraction of the Proton Charge Radius from Electron Scattering by Cui, Zhu-Fang, Binosi, Daniele, Roberts, Craig D., Schmidt, Sebastian M.

“…We present a novel method for extracting the proton radius from elastic electron-proton (ep) scattering data. The approach is based on interpolation via…”

Perspective on the Origin of Hadron Masses by Roberts, Craig D.

“…The energy–momentum tensor in chiral QCD, T μ ν , exhibits an anomaly, viz. Θ 0 : = T μ μ ≠ 0 . Measured in the proton, this anomaly yields m p 2 , where m p…”

Colloquium: Roper resonance: Toward a solution to the fifty year puzzle by Burkert, Volker D, Roberts, Craig D

“…Discovered in 1963, the Roper resonance appears to be an exact copy of the proton except that its mass is 50% greater and it is unstable. These features of the…”
