Hide and seek: how PDFs can conceal New Physics / Hammou, Elie (Cambridge U., DAMTP) ; Kassabov, Zahari (Cambridge U., DAMTP) ; Madigan, Maeve (Heidelberg U.) ; Mangano, Michelangelo L. (CERN) ; Mantani, Luca (Cambridge U., DAMTP) ; Moore, James (Cambridge U., DAMTP) ; Alvarado, Manuel Morales (Cambridge U., DAMTP) ; Ubiali, Maria (Cambridge U., DAMTP)
The interpretation of LHC data, and the assessment of possible hints of new physics, require the precise knowledge of the proton structure in terms of parton distribution functions (PDFs). We present a systematic methodology designed to determine whether and how global PDF fits might inadvertently 'fit away' signs of new physics in the high-energy tails of the distributions. [...]

SMEFT analysis of m$_{W}$ / Bagnaschi, Emanuele (CERN) ; Ellis, John (CERN ; King's Coll. London ; NICPB, Tallinn) ; Madigan, Maeve (Cambridge U., DAMTP) ; Mimasu, Ken (CERN) ; Sanz, Veronica (Valencia U., IFIC ; Sussex U.) ; You, Tevong (King's Coll. London ; Cambridge U., DAMTP ; Cambridge U.)
We use the Fitmaker tool to incorporate the recent CDF measurement of $m_W$ in a global fit to electroweak, Higgs, and diboson data in the Standard Model Effective Field Theory (SMEFT) including dimension-6 operators at linear order. We find that including any one of the SMEFT operators ${\cal O}_{HWB}$, ${\cal O}_{HD}$, ${\cal O}_{\ell \ell}$ or ${\cal O}_{H \ell}^{(3)}$ with a non-zero coefficient could provide a better fit than the Standard Model, with the strongest pull for ${\cal O}_{HD}$ and no tension with other electroweak precision data.

Publishing statistical models: Getting the most out of particle physics experiments / Cranmer, Kyle (New York U.) ; Kraml, Sabine (LPSC, Grenoble) ; Prosper, Harrison B. (Florida State U.) ; Bechtle, Philip (Bonn U.) ; Bernlochner, Florian U. (Bonn U.) ; Bloch, Itay M. (Tel Aviv U.

The statistical models used to derive the results of experimental analyses are of incredible scientific value and are essential information for analysis preservation and reuse. In this paper, we make the scientific case for systematically publishing the full statistical models and discuss the technical developments that make this practical. [...]

Parton distributions in the SMEFT from high-energy Drell-Yan tails / Greljo, Admir (U. Bern, AEC ; CERN) ; Iranipour, Shayan (Cambridge U., DAMTP) ; Kassabov, Zahari (Cambridge U., DAMTP) ; Madigan, Maeve (Cambridge U., DAMTP) ; Moore, James (Cambridge U., DAMTP) ; Rojo, Juan (Vrije U., Amsterdam ; NIKHEF, Amsterdam) ; Ubiali, Maria (Cambridge U., DAMTP) ; Voisey, Cameron (Cambridge U.)
The high-energy tails of charged- and neutral-current Drell-Yan processes provide important constraints on the light quark and anti-quark parton distribution functions (PDFs) in the large-x region. At the same time, short-distance new physics effects such as those encoded by the Standard Model Effective Field Theory (SMEFT) would induce smooth distortions to the same high-energy Drell-Yan tails.

Top, Higgs, Diboson and Electroweak Fit to the Standard Model Effective Field Theory / Ellis, John (King's Coll. London ; CERN ; NICPB, Tallinn) ; Madigan, Maeve (Cambridge U., DAMTP) ; Mimasu, Ken (King's Coll. London) ; Sanz, Veronica (Valencia U., IFIC ; Sussex U.) ; You, Tevong (CERN ; Cambridge U., DAMTP ; Cambridge U.)
The search for effective field theory deformations of the Standard Model (SM) is a major goal of particle physics that can benefit from a global approach in the framework of the Standard Model Effective Field Theory (SMEFT). For the first time, we include LHC data on top production and differential distributions together with Higgs production and decay rates and Simplified Template Cross-Section (STXS) measurements in a global fit, as well as precision electroweak and diboson measurements from LEP and the LHC, in a global analysis with SMEFT operators of dimension 6 included linearly.
