Snowmass Theory Frontier Report
N. Craig, C. Csáki, A. X. El-Khadra +38
This report summarizes the recent progress and promising future directions in theoretical high-energy physics (HEP) identified within the Theory Frontier of the 2021 Snowmass Proce…
Structure of two-loop SMEFT anomalous dimensions via on-shell methods
Zvi Bern, Julio Parra-Martinez, Eric Sawyer
We describe on-shell methods for computing one- and two-loop anomalous dimensions in the context of effective field theories containing higher-dimension operators. We also summariz…
Non-renormalization and operator mixing via on-shell methods
Zvi Bern, Julio Parra-Martinez, Eric Sawyer
Using on-shell methods, we present a new perturbative non-renormalization theorem for operator mixing in massless four-dimensional quantum field theories. By examining how unitarit…
Extrapolating W-Associated Jet-Production Ratios at the LHC
Z. Bern, L. J. Dixon, F. Febres Cordero +4
Electroweak vector-boson production, accompanied by multiple jets, is an important background to searches for physics beyond the Standard Model. A precise and quantitative understa…
Universality in W+Multijet Production
Z. Bern, L. J. Dixon, F. Febres Cordero +5
We study -boson production accompanied by multiple jets at 7 TeV at the LHC. We study the jet-production ratio, of total cross sections for +- to +()-jet productio…
High multiplicity processes with BlackHat and Sherpa
Jeppe R. Andersen, Stephanie Bartle, Zvi Bern +7
In this contribution, we present an intermediate storage format for next-to-leading order (NLO) events and explain the advantages of presenting a NLO calculation in this format. We…
