The Construction of the Higgs Mechanism and the Emergence of the Electroweak Theory [PDF]

, 2011
I examine the construction process of the Higgs mechanism and its subsequent use by Steven Weinberg to formulate the electroweak theory in particle physics.

Alternate computation of gravitational effects from a single loop of inflationary scalars

Journal of High Energy Physics
We present a new computation of the renormalized graviton self-energy induced by a loop of massless, minimally coupled scalars on de Sitter background. Our result takes account of the need to include a finite renormalization of the cosmological constant,

Renormalization for one-loop diagrams in gauge theory.

, 2013
In most situations, calculations of Feynman diagrams which contain loops lead to infinities. Renormalization has been known to be a standard process to circumvent this difficulty. In this project, we studied two different regularization schemes, which are

Effective potential and vacuum stability in the Litim-Sannino model

Journal of High Energy Physics
We revisit the scalar potential in the Litim-Sannino model. We compute for the first time the full quantum corrections to the classical potential and show that they significantly ameliorate the stability analysis at the UV fixed point.

Higher $\varepsilon$-poles and logarithms in the MS-like schemes from the algebraic structure of the renormalization group

We investigate the structure of renormalization constants within the MS-like renormalization prescriptions for a version of dimensional regularization in which the dimensionful regularization parameter $\Lambda$ differs from the renormalization point ...
