Longitudinal, Azimuthal and Multiplicity Dependences of Mean Transverse Momentum and Transverse Momentum Correlations in {pi}+p and K+p Collisions at 250GeV/c

Rapidity, azimuthal and multiplicity dependence of inclusive mean transverse momentum and transverse momentum correlation is studied in {pi}+p and K+p collisions at 250 GeV/c. It is found for the first time that rapidity dependence of two-particle transverse momentum correlations is different from those of inclusive mean transverse momentum but both have similar multiplicity dependence. In particular, the transverse momentum correlation is boost-invariant. The strong azimuthal dependence of transverse momentum correlation comes from the constraint of energy-momentum conservation. The results are compared with those from the PYTHIA Monte Carlo generator. The similarities and differences with those from current heavy ion experiments are discussed.
