Hidden self-energy contributions of collinear functions in SCET
Geoffrey T. Bodwin, June-Haak Ee, Daekyoung Kang +1
The LSZ reduction formula requires one to identify and amputate complete propagators on external legs of a Green's function and to evaluate complete two-point functions in the mass…
Gauge invariance of radiative jet functions in the position-space formulation of SCET
Geoffrey T. Bodwin, June-Haak Ee, Daekyoung Kang +1
In subleading powers of soft-collinear effective theory (SCET), the Lagrangian contains couplings between soft quarks and hard-collinear quarks. Matrix elements of the hard-colline…
Renormalization of the radiative jet function
Geoffrey T. Bodwin, June-Haak Ee, Jungil Lee +1
We show how to compute directly the renormalization/evolution of the radiative jet function that appears in the factorization theorems for and through a …
Analyticity, renormalization, and evolution of the soft-quark function
Geoffrey T. Bodwin, June-Haak Ee, Jungil Lee +1
We compute the renormalization and evolution of the soft-quark function that appears in the factorization theorem for Higgs-boson decays to two photons through a -quark loop. Ou…
New method for fitting coefficients in standard model effective theory
Geoffrey T. Bodwin, Hee Sok Chung
We present an alternative method for carrying out a principal-component analysis of Wilson coefficients in standard model effective field theory (SMEFT). The method is based on sin…
Covariant calculation of a two-loop test of nonrelativistic QCD factorization
Geoffrey T. Bodwin, Hee Sok Chung, June-Haak Ee +2
We test the nonrelativistic QCD factorization conjecture for inclusive quarkonium production at two loops by carrying out a covariant calculation of the nonrelativistic quantum chr…
