Description

In the search for new physics beyond the Standard Model, theorists increasingly rely on Effective Field Theory (EFT) to interpret experimental observations. Driven by the growing experimental sensitivity of several experiments at the intensity frontier and by the recent development of new theoretical and computational techniques, EFT has become an essential framework in any phenomenological study. 

New theoretical techniques have arisen in the past years, providing genuine advancements in the field and more pristine and accessible frameworks. Furthermore, new tools have been developed that automate well-understood but computationally demanding parts of EFT analyses, each forming a link in the chain that is a complete analysis. As the various tools and techniques are reaching maturity, the time is ripe to move part of the focus to better cross-integration of the different parts, which have been developed independently.

The aim of the Scientific Program is to bring the EFT theory community together to discuss recent developments in EFT methods and tools and to kick-start work towards better integration of the various tools into a single software suite. The program will include plenty of time for further discussion among participants and for pursuing new ideas sparked during the talks. The program aims at facilitating a better understanding of the latest theoretical developments, with emphasis on the possible integration into software packages, and establishing better interfaces among the various EFT tools.

      Recent developments on the all-orders renormalization of EFTs 2413/2-430 - MITP Seminar Room

      We present the tools needed to carry out the all-orders renormalization of some classes of EFTs directly relevant to BSM physics. The approach is based on the introduction of dynamical gauge-invariant fields in loop integrals. New relations among Green's functions arise, encoded in some novel differential equations. In favorable cases these equations lead to complete resummation of the dependence of amplitudes on the BSM parameters (at fixed loop order). New phenomena arise with a qualitativey different behaviour of
      the amplitudes, evaluated in the standard linearized approximation in the BSM parameters, compared with the resummed amplitudes.

      An Algebraic Formula for Two Loop Renormalization of Scalar Quantum Field Theory 2413/2-430 - MITP Seminar Room

      We give a general formula for the two-loop renormalization counterterms of a scalar quantum field theory with interactions containing up to two derivatives, which extends 't Hooft's one-loop result. We show that factorizable topologies do not contribute to the renormalization group equations. The results will be combined with the geometric method to obtain the renormalization group equations for the scalar sector of effective field theories to two-loop order.

      These are the minimum number of Lagrangian terms one needs to write SMEFT interactions of dimensions 5 to 15. They are close but not the same as the number of operators for n=1 flavors (2, 84, 30, 993, 560, 15456, 11962, 261485, 257378, 4614554, 5474170, ...). To my knowledge, up to now these numbers were unknown, although I tried to bound them in 1907.12584 [hep-ph]. Note also that the Murphy basis for SMEFT dimension 8 operators contains 1030 terms, 11 more than necessary. I will talk about this and how the computation of such numbers requires studying the permutation group.
