The soft theorem keeps its geometric form, but where the field-space geometry now involves the full field content of the theory. As a bonus, we also present novel double soft theorems with fermions, which mimic

The equality of soft functions in these three different processes, furthermore, extends to many other observables besides event shapes. In Section 2 we review the factorization theorems for event shapes in ee, ep, and pp collisions in which the soft functions that we study appear. In Section ...
however small, in estimating coercivity of bulk magnetic alloys; and we use the ellipsoid and reciprocal theorems to accelerate our coercivity calculations, see16. Our computations are fully three-dimensional with the magnetization evolving from (010) to (100) in all directions as one leaves the ...
Simon (1916-2001) and John Clifford Shaw (1922-1991), the so-called NSS-group††† of the Carnegie-Rand‡‡‡ group, presented on the 1956 founding AI workshop in Dartmouth the Logical Theory Machine, that could proof mathematical theorems in elementary logic, and also when they...
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...
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 ...

Our analysis provides an interesting hierarchy of two-scalar sigma models and soft theorems, ranging from Goldstone boson case to a generic target space, and showing that there are interesting theories in between.
