Electroweak Form Factor in Sudakov and Threshold Regimes with Effective Field Theories
B. Assi, B. A. Kniehl
We compute the massive gauge and scalar corrections to form factors in both the Sudakov and threshold regimes up to and including two-loop orders. The corrections are calculated fo…
Les Houches 2023: Physics at TeV Colliders: Standard Model Working Group Report
J. Andersen, B. Assi, K. Asteriadis +81
This report presents a short summary of the activities of the "Standard Model" working group for the "Physics at TeV Colliders" workshop (Les Houches, France, 12-30 June, 2023).
Massive Two-Loop Heavy Particle Diagrams
B. Assi, B. A. Kniehl, A. I. Onishchenko
We determine the master integrals for vertex and propagator diagrams that appear in effective field theories containing heavy fields. The integrals involve at least one heavy line,…
Matching the Standard Model to Heavy-Quark Effective Theory and Nonrelativistic QCD
B. Assi, B. A. Kniehl, J. Soto
We find the leading electroweak corrections to the Lagrangians of heavy-quark effective theory and nonrelativistic QCD. These corrections appear in the Wilson coefficients of the t…
Static Potential of the Standard Model and Spontaneously Broken Theories
B. Assi, B. A. Kniehl
We consider the static potential in theories exhibiting spontaneous symmetry breaking. We use our findings to calculate the static potential of the Standard Model at one-loop order…
