Pramana63:1391-1406,2004 This is the report of neutrino and astroparticle physics working group at
WHEPP-8. We present the discussions carried out during the workshop on selected
topics in the above ...fields and also indicate progress made subsequently. The
neutrino physics subgroup studied the possibilites of constraining neutrino
masses, mixing and CPT violation in lepton sector from future experiments.
Neutrino mass models in the context of abelian horizontal symmetries, warped
extra dimensions and in presence of triplet Higgs were studied. Effect of
threshold corrections on radiative magnification of mixing angles was
investigated. The astroparticle physics subgroup focused on how various
particle physics inputs affect the CMBR fluctuation spectrum, and on brane
cosmology. This report also contains an introduction on how to use the publicly
available code CMBFAST to calculate the CMBR fluctuations.
Pramana63:1331-1354,2004 This is a summary of the projects undertaken by the Working Group I on High
Energy Collider Physics at the Eighth Workshop on High Energy Physics
Phenomenology (WHEPP8) held ...at the Indian Institute of Technology, Mumbai,
January 5-16, 2004. The topics covered are (i) Higgs searches (ii)
supersymmetry searches (iii) extra dimensions and (iv) linear collider.
This report summarizes a study of the physics potential of the CLIC e+e-
linear collider operating at centre-of-mass energies from 1 TeV to 5 TeV with
luminosity of the order of 10^35 cm^-2 s^-1. ...First, the CLIC collider complex
is surveyed, with emphasis on aspects related to its physics capabilities,
particularly the luminosity and energy, and also possible polarization,
\gamma\gamma and e-e- collisions. The next CLIC Test facility, CTF3, and its
R&D programme are also reviewed. We then discuss aspects of experimentation at
CLIC, including backgrounds and experimental conditions, and present a
conceptual detector design used in the physics analyses, most of which use the
nominal CLIC centre-of-mass energy of 3 TeV. CLIC contributions to Higgs
physics could include completing the profile of a light Higgs boson by
measuring rare decays and reconstructing the Higgs potential, or discovering
one or more heavy Higgs bosons, or probing CP violation in the Higgs sector.
Turning to physics beyond the Standard Model, CLIC might be able to complete
the supersymmetric spectrum and make more precise measurements of sparticles
detected previously at the LHC or a lower-energy linear e+e- collider:
\gamma\gamma collisions and polarization would be particularly useful for these
tasks. CLIC would also have unique capabilities for probing other possible
extensions of the Standard Model, such as theories with extra dimensions or new
vector resonances, new contact interactions and models with strong WW
scattering at high energies. In all the scenarios we have studied, CLIC would
provide significant fundamental physics information beyond that available from
the LHC and a lower-energy linear e+e- collider, as a result of its unique
combination of high energy and experimental precision.
Theoretical progress in Higgs boson production and background processes is
discussed with particular emphasis on QCD corrections at and beyond
next-to-leading order as well as next-to-leading order ...electroweak corrections.
The residual theoretical uncertainties of the investigated processes are
estimated in detail. Moreover, recent investigations of the MSSM Higgs sector
and other extensions of the SM Higgs sector are presented. The potential of the
LHC and a high-energy linear e+e- collider for the measurement of Higgs
couplings is analyzed.
