Proton–Proton and Proton–Antiproton Colliders

Reviews of Accelerator Science and Technology, 2014
In 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 ...

Theory of Scattering of Protons by Protons

Physical Review, 1936
The experiments of Tuve, Heydenburg and Hafstad and those of White are discussed by means of the standard theory of scattering in central fields. The theoretical formulas are presented in a form convenient for numerical computation and are supplemented by tables.

The Scattering of Protons by Protons [PDF]

Physical Review, 1939
The cross section for scattering of protons by protons has been measured at angles from 15\ifmmode^\circ\else\textdegree\fi{} to 45\ifmmode^\circ\else\textdegree\fi{} for protons of energies 860, 1200, 1390, 2105 and 2392 kev. Observed scattering cross sections at 15\ifmmode^\circ\else\textdegree\fi{} are close to Mott values for all energies.

When Is a Proton Not a Proton?

Chemistry - A European Journal, 1998
In spite of the large number of protonated complexes, their use in catalytic cycles has been little explored. The existing examples suggest that catalytic processes initiated by the protonation of a low-valent metal hold promise for the development of selective, efficient, and atom-economical addition reactions under very mild conditions, if the ...

Scattering of Protons by Protons

Physical Review, 1953
The data of Worthington, McGruer, and Findley (WMF) on scattering of protons by protons show an apparently real contribution to the cross section arising from scattering in the $p$ state. Results of phase shift analysis of these data are presented in Table I and in Fig. 1.

Proton-proton bremsstrahlung with polarized protons

2008
The 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

The scattering of protons by protons and the meson field of the proton

Physica, 1948
Abstract New calculations are made on the scattering of protons by protons with several values of the potential energy of the proton, this energy being assumed to be the meson potential. The results of these calculations are compared with the available experimental material.

Noncoplanarity in proton-proton bremsstrahlung

Physical Review C, 2001
Using the soft-photon approximation, we address the issue of the importance of noncoplanarity effects in proton-proton bremsstrahlung, We investigate the noncoplanar cross section as a function of the noncoplanarity angle (φ) over bar for the entire range of the photon polar angle psi(gamma).

Collective proton transport with weak proton-proton coupling

Physical Review E, 2000
A mechanism based on the peculiar dynamical properties of the hydrogen bond is suggested to describe fast proton transfers in hydrogen-bonded chains with realistic (weak) intersite proton-proton interactions. For this purpose, a two-sublattice model is suggested and studied analytically that admits an exact soliton solution.

Theory of Proton-Proton Bremsstrahlung

Physical Review, 1966
The proton-proton bremsstrahlung cross section is derived to first order in the electromagnetic interaction and the nucleon-nucleon $t$ matrix. The cross section is expressed in terms of the nucleon-nucleon phase shifts and the quasi-phase parameters needed to describe $t$ off the energy shell. The formulas are given in a form suitable for calculation.
