One should keep in mind that the limit under consideration is not exactly a heavy-mass limit for, e.g., the top quark (mt →∞ would imply strong coupling), but rather a small-coupling limit for the Higgs self-coupling. The use of effective field theory methods in this limit for the...

As such, celestial gluon (or photon) scattering cannot obey the usual (energetically) soft theorems. In this paper we show that tree-level celestial gluon scattering, in theories with sufficiently soft UV behavior, instead obeys conformally soft theorems involving h → 0 or h → 0. Unlike the...
FIELD-THEORY2 DIMENSIONSWEAK DECAYSQUARKQCDSYMMETRYDISTRIBUTIONSFACTORIZATIONThe main application of heavy quark effective theory (HQET) and of soft collinear effective theory (SCET) is in establishing factorization theorems for exclusive and semi-inclusive decays of heavy mesons. However, the calculation ...
It is argued that SCET, as it stands, is not capable to define in a gauge invariant way certain non-perturbative matrix elements that are an integral part of many factorization theorems. Those matrix elements involve two quark or gluon fields separated not only in light-cone direction but ...
In this paper, we derive a soft photon theorem and a soft gluon theorem in the de Sitter spacetime from the Ward identity of the near cosmological horizon large gauge transformation. Taking the flat limit of the de Sitter spacetime, the soft theorems naturally recover the corresponding flat spac...
