Abstract:
Measurements from ISR, SPS, Tevatron ineluding most recent measurements by E-
81 1 collaboration and future measurements from PP2PP at RH1C as well as from
CMS, and TOTEM at LHC throws light on various aspects of elastic and diffractive
scattering. We have analysed the world data for proton-proton and proton-antiproton
scattering in the light of predictions of various models with special focus on Eikonal
picture and QCD inspired models. Special emphasis has been given on the shrinkage
of the diffraction peak and dip structure in the differential cross section besides
encompassing other physical parameters. These parameters have been computed in
the light of Generalized Chou-Yang model and compared with other models with
special emphasis on the possibility of multiple dip structure at RH1C and LHC
energies. Role of p, ration of the real and imaginary parts of the scattering amplitude,
in the appearance or otherwise of multiple structure has also been considered. At the
same time, presence of Odderon at high energy has been in question for quite some
time. Wc have probed the Odderon description in theory and possibility of its search
at the current and future colliders. The Odderon in perturbative and non-perturbative
QCD has been discussed along with some phenomenological approaches. A
comparison of the Odderon description with other models has also been made with
the available data including measurements from cosmic ray. which corresponds to the
LHC energy of 14 TeV and beyond. Our sludy also focuses on the measurements at
RHTC and LHC and the presence or otherwise of Odderon, In the light of this
analysis, suggestions for future measurements have been made.
