HIGH ENERGY PHYSICS; STUDIES FROM V. KHACHATRYAN ET AL FURTHER UNDERSTANDING OF HIGH ENERGY PHYSICS

"on two-particle angular correlations for charged particles emitted
in proton-proton collisions at center-of-mass energies of 0.9, 2.36,
and 7TeV are presented, using data collected with the CMS detector
over a broad range of pseudorapidity (eta) and azimuthal angle (phi),"
scientists writing in the Journal of High Energy Physics report.
"Short-range correlations in Delta(eta), which are studied in minimum
bias events, are characterized using a simple "independent cluster"
parametrization in order to quantify their strength (cluster size)
and their extent in eta (cluster decay width). Long-range azimuthal
correlations are studied differentially as a function of charged
particle multiplicity and particle transverse momentum using a 980
nb(-1) data set at 7TeV," wrote V. Khachatryan and colleagues.
The researchers concluded: "In high multiplicity events, a pronounced
structure emerges in the two-dimensional correlation function for
particle pairs with intermediate p(T) of 1-3 GeV/c, 2.0
