Constructing operator basis in supersymmetry: a Hilbert series approach
Journal of High Energy Physics, 2023 In this paper we introduce a Hilbert series approach to build the operator basis for a N = 1 supersymmetry theory with chiral superfields. We give explicitly the form of the corrections that remove redundancies due to the equations of motion and ...

Nonrelativistic effective field theory with a resonance field [PDF]
The European Physical Journal A, 2021 We discuss shallow resonances in the nonrelativistic scattering of two particles using an effective field theory (EFT) that includes an auxiliary field with the quantum numbers of the resonance. We construct the manifestly renormalized scattering amplitude up to next-to-leading order in a systematic expansion.

Effective field theory for leptoquarks
Journal of High Energy Physics, 2023 Abstract Leptoquarks enter in several extensions of the Standard Model as possible solutions to a number of observed anomalies. We work within the soft-collinear effective theory framework to present a detailed analysis of the decay rates of the three leptoquarks that appear the most in literature, the scalars S1 and S3 and the ...

Spin supplementary condition in quantum field theory: covariant SSC and physical state projection
Journal of High Energy Physics, 2023 The spin supplementary conditions are constraints on spin degrees of freedom in classical relativity which restricts physical degrees of freedom to rotations.

On the development of effective field theory [PDF]
The European Physical Journal H, 2021 AbstractEditor’s note: One of the most important developments in theoretical particle physics at the end of the 20th century and beginning of the twenty-first century has been the development of effective field theories (EFTs). Pursuing an effective field theory approach is a methodology for constructing theories, where a set of core principles is ...

Bell violation in 2 → 2 scattering in photon, gluon and graviton EFTs
Journal of High Energy Physics, 2023 In this paper, we explore Bell inequality violation for 2 → 2 scattering in Effective Field Theories (EFTs) of photons, gluons, and gravitons. Using the CGLMP Bell parameter (I 2), we show that, starting from an appropriate initial non-product state, the

Effective field theories with instantons [PDF]
Nuclear Physics B, 1994 We explain how nonperturbative effects can be systematically included when constructing an effective field theory. We concentrate in particular on the matching calculation, by which a low energy theory without a heavy particle degree of freedom is matched onto the full theory.
