This paper presents STrEAM (SuperTrace Evaluation Automated for Matching), a Mathematica package that calculates all functional supertraces which arise when matching a generic UV model onto a relativistic Effective Field Theory (EFT) at one loop and to arbitrary order in the heavy mass expansion. STrEAM implements the covariant derivative expansion to automate the most tedious step of the streamlined functional matching prescription presented in arXiv:2011.02484 . The code and an example notebook are available at https://www.github.com/EFTMatching/STrEAM .
We simplify the one-loop functional matching formalism to develop a streamlined prescription. The functional approach is conceptually appealing: all calculations are performed within the UV theory at the matching scale, and no prior determination of
We present SuperTracer, a Mathematica package aimed at facilitating the functional matching procedure for generic UV models. This package automates the most tedious parts of one-loop functional matching computations. Namely, the determination and eva
We investigate the sensitivity of the FASER$ u$ detector to new physics in the form of non-standard neutrino interactions. FASER$ u$, which has recently been installed 480 m downstream of the ATLAS interaction point, will for the first time study int
We use effective field theory to compute the influence of nuclear structure on precision calculations of atomic energy levels. As usual, the EFTs effective couplings correspond to the various nuclear properties (such as the charge radius, nuclear pol
We discuss the possible validity in QCD of a relation between Greens functions which has been recently suggested by Son and Yamamoto, based on a class of AdS/CFT-inspired models of QCD. Our conclusion is that the relation in question is unlikely to be implemented in QCD.
