“…One interpretation of these data is that a leading nucleon typically carries away half of the beam energy. In p+p collisions, the x F of the leading proton was found to directly anticorrelate with the particle multiplicity, as if the leading particle simply removed energy that would otherwise go into particle production [133,134,135]. By rescaling the center-of-mass energy for the p+p data by a factor of two (see open diamonds in Fig.…”

This paper describes the conclusions that can be drawn from the data taken thus far with the PHOBOS detector at RHIC. In the most central Au+Au collisions at the highest beam energy, evidence is found for the formation of a very high energy density system whose description in terms of simple hadronic degrees of freedom is inappropriate. Furthermore, the constituents of this novel system are found to undergo a significant level of interaction. The properties of particle production at RHIC energies are shown to follow a number of simple scaling behaviors, some of which continue trends found at lower energies or in simpler systems. As a function of centrality, the total number of charged particles scales with the number of participating nucleons. When comparing Au+Au at different centralities, the dependence of the yield on the number of participants at higher p T (∼4 GeV/c) is very similar to that at low transverse momentum. The measured values of charged particle pseudorapidity density and elliptic flow were found to be independent of energy over a broad range of pseudorapidities when effectively viewed in the rest frame of one of the colliding nuclei, a property we describe as "extended longitudinal scaling". Finally, the centrality and energy dependences of several observables were found to factorize to a surprising degree.

“…The momentum distribution of the incident nucleon after n inelastic collisions Dl n '(x n ) is related to that after (n-1) inelastic collisions Di^'fxn.i) by where the function w{x n _i,x n ) is the probability for finding a "leading" baryon with x n after a baryon-baryon inelastic collision if the initial Feynman scaling variable is x n _i-Experimental pp+pX data at high energies show a nearly flat 6 and energy-independent 7 differential cross section do/dx as a function of x.

“…[22]. [17], p 0 = 100 GeV/c [60], and p 0 = 158 GeV/c [20] are quite complete in x F and p T and are relevant for this purpose. Additionally, studies of the A dependence of cross sections at 100 GeV/c [48] and 25 GeV/c [99] were used to show a scaling behaviour…”

Neutrino beams at from high-energy proton accelerators have been instrumental discovery tools in particle physics. Neutrino beams are derived from the decays of charged π and K mesons, which in turn are created from proton beams striking thick nuclear targets. The precise selection and manipulation of the π/K beam control the energy spectrum and type of neutrino beam. This article describes the physics of particle production in a target and manipulation of the particles to derive a neutrino beam, as well as numerous innovations achieved at past experimental facilities.
