Systems of particles that interact only through excluded volume interactions are minimal models to study entropydriven phase transitions. In this thesis we study in detail two hard core lattice gas models on the square ...

Polyelectrolytes (PEs) are polymers whose monomers contain ionizable groups that dissociate in polar solvents, releasing charged counterions into the solvent, thereby making the polymer backbone charged. The thermodynamic ...

With LHC discovering a scalar behaving like the standardmodel (SM) Higgs marks the completion (tentatively at least) of all the particles predicted by SM and validation of the fundamental principles upon which it is built, ...

In this thesis, we briefly discuss some theoretical shortcomings of the Standard Model (SM) and motivate the need for beyond
the SM (BSM) physics. Many BSM extensions predict the existence of new heavy fermions with masses ...

The New Physics, the Physics beyond the Standard Model, shows that New Physics which affects B decays with any topological amplitude can be absorbed by redefinitions of the SM amplitudes. This thesis studies the B → K∗ρ ...

This thesis is structured as follows. In Chapter 2 of the thesis, the LowSkibaSmith
(LSS) model i.e. the SU (6)/Sp(6) littleHiggs model is studied in detail along with a brief discussion on various littleHiggs models, ...

Living entities perpetually exist away from equilibrium, a condition necessary for the
proper functioning of crucial biological and biochemical processes. Tools from nonequilibrium physics are thus ideally suited to the ...
