The present status of supersymmetric models in the aftermath of the Higgs boson discovery will be discussed. Prospects for discovery of supersymmetry at future colliders and possible probes of the decoupling limit will also be described. Somealternatives to supersymmetry will be briefly touched upon.

Deceptive lattice spacings in HRTEM Imaging of nanocrystals
Abstract
In nano particle, length of the atomic column varies from centerof the grain to the edge which resulted in curved lattice planes (off zoneaxis tilting) and delocalization (can be solved using Cs correctedmicroscope). Overlap of the top atomic column with bottom of an adjacentcolumn give rise to fringe pattern having deceptive lattice spacing. Inthis talk, we will discuss the various reasons for the deceptive latticespacing in HRTEM imaging and its rectification.This technique will help usin analyzing the strain and composition of bimetallic nanoparticles withmore accuracy. In addition to this, we will discuss about the Precessionelectron Diffraction technique(PED) which is an advanced TEM technique foranalyzing the strain in bulk and thin film samples.
