WebA bstractIn this article we extend the effective field theory framework describing new physics effects to the case where the underlying low-energy theory is a Two-Higgs-Doublet model. We derive a complete set of independent operators up to dimension six assuming a Z2-invariant CP-conserving Higgs potential. The effects on Higgs and gauge boson … Effective field theories typically work best when there is a large separation between length scale of interest and the length scale of the underlying dynamics. Effective field theories have found use in particle physics, statistical mechanics, condensed matter physics, general relativity, and hydrodynamics.

WebIn physics, specifically field theory and particle physics, the Proca action describes a massive spin -1 field of mass m in Minkowski spacetime. The corresponding equation is a relativistic wave equation called the Proca equation. [1] The Proca action and equation are named after Romanian physicist Alexandru Proca . WebThese subjects have been intensively studied over the past decade, largely motivated by rapid progress in the field of observational cosmology that now allows, for the first time, precision tests of fundamental physics on the scale of the observable Universe.
