Operator Regularization And Renormalization Theory [PDF]

, 1989
In the past few years a new method of regularization, called operator regularization (o.r.), has been developed to regulate formal divergences that arise in quantum field theory. This technique is characterized by the fact that no divergent quantities ever arise once the technique is applied, even after the regulating parameter approaches its limiting ...

Soft factorisation and exponentiation from Schwinger-space geometry

Journal of High Energy Physics
Infrared divergences in Quantum Field Theory govern the low-energy dynamics of many physical theories, and their understanding is a crucial ingredient in predicting the outcomes of collider experiments.

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.

Non-perturbative renormalisation and improvement of non-singlet tensor currents in N f = 3 QCD

Journal of High Energy Physics
Hadronic matrix elements involving tensor currents play an important rôle in decays that allow to probe the consistency of the Standard Model via precision lattice QCD calculations. The non-singlet tensor current is a scale-dependent (anomalous) quantity.

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,
