Long-range multiplicity correlations in proton-proton collisions
The forward-backward long-range multiplicity correlations in proton-proton
collisions are investigated in the model with two independent sources of
particles: one left- and one right-moving wounded nucleon. A good agreement
with the UA5 collaboration proton-antiproton data at the c.m. energy of 200 GeV
is observed. For comparison the model with only one source of particles is also
discussed.Comment: 11 pages, 5 figure
Wounded quark-diquark model predictions for heavy ion collisions at the LHC
The ratios of particle densities in lead-lead and proton-lead collisions to
particle density in proton-proton collision in the central rapidity region at
the LHC energy are predicted on the basis of wounded quark-diquark model.Comment: 9 pages, 2 figure
Charged pions multiplicities at the NA49 energy
The wounded quark-diquark model predictions for charged pions multiplicities
in PbPb and pPb collisions in the central rapidity region at sqrt(s)=17.3 GeV
c.m. energy are presented.Comment: 4 pages, 4 figure
Production of gluon jets in pp collisions by double pomeron exchange in the Landshoff-Nachtmann model
Using the Landshoff-Nachtmann two-gluon exchange model of the pomeron, the
double pomeron exchange contribution to production of gluon pairs in the
central region of rapidity is calculated. The results are compared with those
for production of quark-antiquark pairs.Comment: 11 pages, 8 figures. Submitted to Acta Phys. Pol.
The diquark and elastic pion-proton scattering at high energies
Small momentum transfer elastic pion-proton cross-section at high energies is
calculated assuming the proton is composed of two constituents, a quark and a
diquark. We find that it is possible to fit very precisely the data when (i)
the pion acts as a single entity (no constituent quark structure) and (ii) the
diquark is rather large, comparable to the size of the proton.Comment: 9 pages, 4 figure
Multi-particle correlations in transverse momenta from statistical clusters
We evaluate -particle () transverse momentum correlations for
pions and kaons following from the decay of statistical clusters. These
correlation functions could provide strong constraints on a possible existence
of thermal clusters in the process of particle production.Comment: 7 pages, 3 figures; published versio
