Strangeness production in proton-proton and proton-nucleus collisions [PDF]

Pramana, 2005
In these lectures we discuss the investigation of the strange meson production in proton-proton ($pp$) and in proton-nucleus ($pA$) reactions within an effective Lagrangian model. The kaon production proceeds mainly via the excitations of $N^*$(1650), $N^

The strangest proton? [PDF]

The European Physical Journal C, 2020
AbstractWe present an improved determination of the strange quark and antiquark parton distribution functions of the proton by means of a global QCD analysis that takes into account a comprehensive set of strangeness-sensitive measurements: charm-tagged cross sections for fixed-target neutrino–nucleus deep-inelastic scattering, and cross sections for ...

Leptons in the proton [PDF]

Journal of High Energy Physics, 2020
Abstract As is the case for all light coloured Standard Model particles, also photons and charged leptons appear as constituents in ultrarelativistic hadron beams, and admit a parton density function (PDF). It has been shown recently that the photon PDF can be given in terms of the structure functions and form factors for electron ...

Polarized Proton-Proton Bremsstrahlung [PDF]

Physical Review Letters, 1986
Abstract A proton-proton bremsstrahlung experiment recently carried out at TRIUMF with polarized protons gives results which disagree with the Soft Photon Approximation and agree with potential model calculations.

The Proton-Proton Interaction [PDF]

Physical Review, 1950
This paper presents a phenomenological analysis of the proton-proton scattering observed at 32 and 340 Mev in terms of static nuclear potentials. Comparison of these results with the neutron-proton scattering at 40, 90, and 280 Mev analyzed previously indicates that nuclear forces are not charge independent. In particular, there is definite evidence in

Proton-proton interactions and onset of deconfinement [PDF]

Physical Review C, 2020
The experiment of the NA61/SHINE Collaboration at the CERN SPS is performing a unique study of the phase diagram of strongly interacting matter by varying collision energy and nuclear mass number of colliding nuclei. In central Pb+Pb collisions, the experiment of the NA49 Collaboration found structures in the energy dependence of several observables in

On the Equality of the Proton-Proton and Proton-Neutron Interactions [PDF]

Physical Review, 1939
A comparison of the 1S proton-proton interaction and the 1S proton-neutron interaction has been made recently by Breit, Hoisington, Share, and Thaxton. It is the purpose of this letter to add a remark to the subject. With the meson type of potential, [C x e^(-lambda x r)]/r x lambda, a variational calculation has been made of the binding energy of H3 ...

Collective exchange processes reveal an active site proton cage in bacteriorhodopsin [PDF]

, 2020
Proton translocation across membranes is vital to all kingdoms of life. Mechanistically, it relies on characteristic proton flows and modifications of hydrogen bonding patterns, termed protonation dynamics, which can be directly observed by fast magic ...
