Description
Electroweak Theory (EWT) allows the existence of BNV processes mediated by topologically non-trivial field configurations. The most well-known such configuration is the instanton. However, due to the breaking of scale invariance by the Higgs mass, instantons are not allowed in EWT. Instead, one must use constrained instantons to obtain the BNV rate.
This poster will explain constrained instanton formalism and its application to the calculation of the tunnelling rate. It will also show the results of such calculation in a toy phi^4 model and explain how the formalism can be extended to EWT
