31. Putting SMEFT Fits to Work

Dr Samuel Homiller (Harvard University)

24. $A_{FB}$ in the SMEFT: the LHC as a Z-physics laboratory

Mr Víctor Bresó (Universitat de Valencia)

14/04/2021, 20:35

We study the forward-backward asymmetry $A_{FB}$ in $pp \rightarrow l^+l^-$ at the Z peak within the Standard Model Effective Field Theory (SMEFT). We find that this observable provides per mille level constraints on the vertex corrections of the Z boson to quarks, which close a flat direction in the electroweak precision SMEFT fit. Moreover, we show that current $A_{FB}$ data is precise...

18. Reviving the interference: framework and proof-of-principle for the anomalous gluon self-interactions in the SMEFT

Mr Matteo Maltoni (UCLouvain)

14/04/2021, 21:00

Interferences between Standard Model (SM) and new physics effective operators are not positive-definite and therefore they can change sign over the phase space. If the contributions of the regions where the interference is positive and negative nearly cancel each other, interference effects are hard to measure. In this talk, I will present a brand-new method, based on the matrix element, to...

20. Precision from Diboson Processes at FCC-hh

Philipp Englert (DESY)

14/04/2021, 21:35

Thanks to its high luminosity and center of mass energy, the future FCC-hh collider will allow us to probe processes with clean but rare final states that are unaccessible at the LHC. The study of diboson production processes poses a promising way of indirectly constraining New Physics in the context of the Higgs Boson. Specifically, the diphoton leptonic decay channels of the Wh and Zh...

32. All things EFT: SMEFT Practicalities

Sally Dawson (BNL)

14/04/2021, 22:00

SMEFT has become the tool of choice for precision searches for new non-resonant physics effects at the LHC and there have been many beautiful theory talks in the All Things EFT series. In this talk, I will discuss some of the issues that arise when attempting to tease out new physics effects from SMEFT studies and I will have more questions than conclusions.  I begin with a discussion of...
