Proton–Proton and Proton–Antiproton Colliders
Reviews of Accelerator Science and Technology, 2014In the last five decades, proton–proton and proton–antiproton colliders have been the most powerful tools for high energy physics investigations. They have also deeply catalyzed innovation in accelerator physics and technology. Among the large number of proposed colliders, only four have really succeeded in becoming operational: the ISR, the SppbarS ...

Proton–proton correlations observed in two-proton radioactivity of 94Ag
Nature, 2006The stability and spontaneous decay of naturally occurring atomic nuclei have been much studied ever since Becquerel discovered natural radioactivity in 1896. In 1960, proton-rich nuclei with an odd or an even atomic number Z were predicted to decay through one- and two-proton radioactivity, respectively.

Hematology/Oncology Clinics of North America, 2019
Proton therapy is a form of external beam radiotherapy that has several advantages over conventional photon (x-ray) radiotherapy. Protons are useful in 2 scenarios that apply to a large proportion of cancer patients: lack of exit dose allows for delivery of a therapeutic radiation dose to tumors in challenging anatomic locations, and reduction in ...

Proton-Proton Bremsstrahlung Calculations
Physical Review, 1969The pole contribution to the proton-proton bremsstrahlung cross section is shown to give the cross section exactly to order ${K}^{0}$, where $K$ is the photon momentum, in the gauge in which the photon polarization ${\ensuremath{\epsilon}}^{\ensuremath{\mu}}$ has ${\ensuremath{\epsilon}}^{0}=0$ in the center-of-mass system.

Proton-proton bremsstrahlung with polarized protons
2008The asymmetry in proton-proton bremsstrahlung is given for a variety of kinematic conditions in the soft photon approximation. It is argued that the asymmetry may be more sensitive to the unknown higher-order terms than the cross section and is shown that several models giving similar cross sections give quite different asymmetries, which could thus be

Proton-proton azohomoallylic interactions
Journal of Magnetic Resonance (1969), 1973Abstract A detailed analysis of the magnetic resonance of pyrazoline ring protons showed the presence of long-range proton-proton interactions through a nitrogen-nitrogen double bond. The magnitude of coupling constants was determined by computer simulation of the spectra and the signs deduced from triple resonance experiments.

This chapter is intended to give an overview of the basics of the description and simulation of proton-proton (pp) collisions. The terminology is introduced in Sect. 4.1. Section 4.2 contains a brief discussion of parton density functions and Sect. 4.3 introduces the basic concepts for the calculation of hadron–hadron cross sections.

QCD in High-Energy Proton-Proton and Proton-Antiproton Collisions
1985The experimental and theoretical investigation of nucleon-nucleon collisions at high energies allows to explore the structure of the nucleon by large momentum transfer (deep-inelastic) processes. In these lectures the structure of the nucleon from momentum scales Q > 1 GeV/c (

Physics in Medicine and Biology, 2006
Proton therapy has become a subject of considerable interest in the radiation oncology community and it is expected that there will be a substantial growth in proton treatment facilities during the next decade. I was asked to write a historical review of proton therapy based on my personal experiences, which have all occurred in the United States, so ...
