“…The recent operation of the Large Hadron pp Collider (LHC) at CERN has opened up the opportunity to examine the R 1D derived from BEC of identical pion pairs produced in pp collisions at very high center of mass energies up to 7 TeV. A set of R 1D values, obtained via equation (1) and taken from [4][5][6][7][8][9] are presented in figure 1 as a function of the pp colliding energy in the range of √ s from 5 GeV to 15 TeV. The errors shown are the statistical and systematic ones added in quadrature.…”

The dependence of the one-dimensional Bose–Einstein correlation R1D derived from proton–proton collisions is examined in terms of energy, hadron multiplicity and number of emerging hadronic jets. It is argued that the observed rise of R1D with energy is the result of the increase of the average number of hadronic jets. It is further shown that by the relatively straightforward measurements of R1D and its chaoticity parameter λ one should be able to estimate the average number of outgoing hadronic jets emitted over the entire final state phase space without the need to rely on a particular jet finding algorithm and its associated parameters.

“…Thus, in the absence of other correlations, C( q) must approach a constant value independent of the magnitude and direction of q; equivalently, A l,m (| q|) must vanish at large | q| for l = 0. However, in elementary particle collisions, additional structure at large relative momentum (| q| 400 MeV/c) has been observed [20,[31][32][33][34][35]. Usually this structure is parametrized in terms of a function ( q) that contributes in addition to the femtoscopic component C F ( q).…”

The STAR Collaboration at the BNL Relativistic Heavy Ion Collider has measured two-pion correlation functions from p + p collisions at √ s = 200 GeV. Spatial scales are extracted via a femtoscopic analysis of the correlations, though this analysis is complicated by the presence of strong nonfemtoscopic effects. Our results are put into the context of the world data set of femtoscopy in hadron-hadron collisions. We present the first direct comparison of femtoscopy in p + p and heavy ion collisions, under identical analysis and detector conditions.

We construct a dynamical model to study the pion correlations in the 5~z annihilation of p/5 at rest. For the resonant channels, the simplest Lorentz-invariant couplings have been used. It is found that, in addition to the Bose-Einstein correlations caused by the finite size of the source, the dynamical correlations from the channels with intermediate resonances are important for explaining the experimental two-pion correlation function. The reliability of two standard methods for pion interferometry is tested in our model.
