We investigate the possibility of detecting a scalar leptoquark, coupling to the electron and the top, at a linear collider. For coupling strength equalling the weak coupling constant, the present mass bounds are of the order of 300 GeV. We demonstrate that at the NLC, one could detect such particles if their mass were less than a few TeV’s. ∗[email protected], [email protected]...

Molecular simulations are used in many areas of biotechnology, such as drug design and enzyme engineering. Despite the development of automatic computational protocols, analysis of molecular interactions is still a major aspect where human comprehension and intuition are key to accelerate, analyze, and propose modifications to the molecule of interest. Most visualization algorithms help the use...

These lectures constitute a short course in ‘Beyond the Standard Model’ for students of experimental particle physics. I discuss the general ideas which guide the construction of models of physics beyond the Standard Model. The central principle, the one which most directly motivates the search for new physics, is the search for the mechanism of the spontaneous symmetry breaking observed in the...

The efficient and accurate quantification of protein-ligand interactions using computational methods is still a challenging task. Two factors strongly contribute to the failure of docking methods to predict free energies of binding accurately: the insufficient incorporation of protein flexibility coupled to ligand binding and the neglected dynamics of the protein-ligand complex in current scori...

To describe the interaction of molecular vibrations with electrons at a quantum dot contacted to metallic leads, we extend an analytical approach that we previously developed for the many-polaron problem. Our scheme is based on an incomplete variational Lang-Firsov transformation, combined with a perturbative calculation of the electron-phonon self-energy in the framework of generalized Matsuba...

Molecular modeling is used effectively in the fields of physics, biochemistry, molecular biology, drug design and interaction, synthesis polymers high quality new substances, both research industrial terms. methods are great importance research, especially theoretical studies. In this study, information given about methods, docking programs.

The new proposed experiment CLEO-c in the Wilson Laboratory at Cornell University will explore the physics potential of the CLEO detector and the CESR storage ring operation in the center-of-mass energy range 3 5 GeV. Data taking could start as early as January 2003. Estimates of the luminosity that a suitably modified CESR can deliver in this energy range imply data samples of 1 4 fb/year. The...
