The size of the proton [PDF]

Nature, 2010
The proton is the primary building block of the visible Universe, but many of its properties-such as its charge radius and its anomalous magnetic moment-are not well understood. The root-mean-square charge radius, r(p), has been determined with an accuracy of 2 per cent (at best) by electron-proton scattering experiments.

Proton-proton Bremsstrahlung

Nuclear Physics B, 1967
Abstract We calculate proton-proton Bremsstrahlung cross sections using the Tabakin separable potentials to generate off-shell nucleon-nucleon t-matrix elements in low partial waves and off-shell one-pion-exchange amplitudes for the higher partial waves.

The rate of the proton-proton reaction

The Astrophysical Journal, 1994
We re-evaluate the matrix element for the proton-proton reaction which is important for stellar-evolution calculations and for the solar-neutrino problem. We self-consistently determine the effect of vacuum polarization on the matrix element by first correcting the low-energy scattering data to account for vacuum polarization.

Successful treatment with proton beam therapy for a solitary sternal metastasis of breast cancer: a case report

Journal of Medical Case Reports, 2022

Transverse spin effects in proton-proton scattering and $Q \bar Q$ production

, 2002
We discuss transverse spin effects caused by the spin-flip part of the Pomeron coupling with the proton. The predicted spin asymmetries in proton-proton scattering and QQ production in proton-proton and lepton-proton reactions are not small and can be ...

Long-term results of a phase II study of hypofractionated proton therapy for prostate cancer: moderate versus extreme hypofractionation

Radiation Oncology, 2019
Background We performed a prospective phase II study to compare acute toxicity among five different hypofractionated schedules using proton therapy. This study was an exploratory analysis to investigate the secondary end-point of biochemical failure-free

Diffusion-controlled generation of a proton-motive force across a biomembrane [PDF]

, 2009
Respiration in bacteria involves a sequence of energetically-coupled electron and proton transfers creating an electrochemical gradient of protons (a proton-motive force) across the inner bacterial membrane. With a simple kinetic model we analyze a redox

Cosmic protons [PDF]

Physics Letters B, 2000
The primary proton spectrum in the kinetic energy range 0.2 to 200 GeV was measured by the Alpha Magnetic Spectrometer (AMS) during space shuttle flight STS–91 at an altitude of 380 km. The complete data set combining three shuttle attitudes and including all known systematic effects is ...
