Hollowness in pp and pp¯ scattering in a Regge model

A Multiparton Model for pp / pp Inelastic Scattering

We have applied a geometrical approach to study pp / pp inelastic scattering over the range of center mass energies from 44.5 to 900 GeV. The multiplicity distributions are described by multiple parton-parton collisions without free parameters. The output seems to be consistent with data and the results are discussed. Exploring the possible connection between impact parameter representation of ...

COULOMB INTERFERENCE IN HIGH-ENERGY pp AND ¯pp SCATTERING.

Role of covalent bond formation in morphology and properties of PP/PP-g-PS binary blends

PP-g-PS copolymer is a typical compatilizer used in polypropylene and polystyrene immiscible blends. PP-g-PS copolymers with different side chain lengths were synthesized, and their thermal and mechanical properties were characterized by differential scanning calorimetry (DSC), polarizing optical microscopy (POM) and dynamic mechanical analysis (DMA), respectively. The DSC and POM results show ...

Production in Polarized pp Scattering and Polarized Gluon Distribution

To extract information about the polarized gluon distribution, ∆G(x,Q), in the nucleons, we propose Λc productions in polarized pp scattering, p+~ p → ~ Λc +X, which will be observed at RHIC experiment starting soon. For this process, we have calculated the spin correlation differential cross section, d∆σ/dp T , and the spin correlation asymmetry defined by ALL ≡ [d∆σ/dpT ]/[dσ/dpT ]. We have f...

The perturbative odderon in elastic pp and pp̄ scattering

The evidence for the existance of an odderon [1] remains scarce. To date, the best evidence comes from the differential cross section in elastic pp and pp̄ scattering. The pp data show a dip structure at −t ≈ 1.3 GeV while the pp̄ data only flatten off at that point. The odderon, being odd under charge conjugation, couples with different signs to protons and antiprotons and can hence account for ...
