Electron and Neutron Electric Dipole Moments in the Focus Point Scenario of SUGRA Model

Utpal Chattopadhyay, Tarek Ibrahim, D. P. Roy

We estimate the electron and neutron electric dipole moments in the focus point scenario of the minimal SUGRA model corresponding to large sfermion masses and moderate to large $\t…

LHC Signature of the Minimal SUGRA Model with a Large Soft Scalar Mass

Utpal Chattopadhyay, Amitava Datta, Anindya Datta +2

Thanks to the focus point phenomenon, it is quite {\it natural} for the minimal SUGRA model to have a large soft scalar mass m_0 > 1 TeV. A distinctive feature of this model is an…

Testing the Randall-Sundrum Model at a High Energy $e^{-} e^{-}$ Collider

Dilip Kumar Ghosh, Sreerup Raychaudhuri

We study the process $e^{-} e^{-} \to e^{-} e^{-}$ at a high energy $e^{-} e^{-}$ collider including the effect of graviton exchanges in the warped gravity model of Randall and Sundrum. Discov…

Signals for Gauge Mediated Supersymmetry Breaking Model at an { $e^{-} e^{-}$ } Collider

Debajyoti Choudhury, Dilip Kumar Ghosh

We study the pair-production and decay of right handed selectrons within a Gauge Mediated Supersymmetry Breaking Model in polarised $e^{-} e^{-}$ interaction. Detailed analyses of the p…

Does LEP prefer the NMSSM?

M. Bastero-Gil, C. Hugonie, S. F. King +2

We study the naturalness of electroweak symmetry breaking and baryogenesis in the next-to-minimal supersymmetric standard model (NMSSM). Our study is motivated by the recent LEP bo…

Quark Mass Corrections to the Perturbative Thrust and its Effect on the determination of $α_{s}$

Sunanda Banerjee, Rahul Basu

We consider the effects of quark masses to the perturbative thrust in $e^{+} e^{-}$ annihilation. In particular we show that perturbative power corrections resulting from non-zero quark…

Constraining Anomaly Mediated Supersymmetry Breaking Framework via Ongoing Muon g-2 Experiment at Brookhaven

Utpal Chattopadhyay, Dilip Kumar Ghosh, Sourov Roy

The ongoing high precision E821 Brookhaven National Laboratory experiment on muon g-2 is promising to probe a theory involving supersymmetry. We have studied the constraints on the…

CP Violation and Dark Matter

Utpal Chattopadhyay, Tarek Ibrahim, Pran Nath

A brief review is given of the effects of CP violation on the direct detection of neutralinos in dark matter detectors. We first summarize the current developments using the cancel…

Large Extra Dimensions at Linear Colliders

K. Sridhar

In this talk, I first present the motivation for theories wherein extra spacetime dimensions can be compactified to have large magnitudes. In particular, I discuss the Arkani-Hamed…

Quark-Gluon Plasma: Status of Heavy Ion Physics

R. V. Gavai

Lattice quantum chromodynamics (QCD), defined on a discrete space time lattice, leads to a spectacular non-perturbative prediction of a new state of matter, called quark-gluon plas…

Study of R-parity-violating supersymmetric signals at an e-e- collider

Dilip Kumar Ghosh, Sourov Roy

We study the pair production of right selectrons at a 500 GeV $e^{-} e^{-}$ collider followed by their decay into an electron and a lightest neutralino. This lightest neutralino decays…

Is the Polarized Antiquark Sea in the Nucleon Flavor Symmetric?

R. S. Bhalerao

We show that the model which naturally explains the $u ˉ \neq = d ˉ$ asymmetry in the nucleon and is in quantitative agreement with the Gottfried sum rule data, also predicts th…

Understanding Fields Using Strings: A Review for Particle Physicists

Sunil Mukhi

In addition to being a prime candidate for a fundamental unified theory of all interactions in nature, string theory provides a natural setting to understand gauge field theories.…

A QCD Analysis of Polarised Parton Densities

Dilip Kumar Ghosh, Sourendu Gupta, D. Indumathi

We present the results of a QCD fit to global data on deep-inelastic polarised lepton-hadron scattering. We find that it is possible to fit the data with strongly broken SU(2) flav…
