Registration closes March 27.

The SM@LHC Workshop brings together theorists and experimenters to discuss the latest developments and future prospects in Standard Model phenomenology at the LHC, with emphasis on the most interesting and topical aspects at the interface between theory and experiment. The workshop has sessions devoted to Electroweak, QCD, Higgs, Top, Heavy Flavour and EFT.

The 2025 edition will take place at the IPPP in Durham (UK).

Previous workshops of the SM@LHC series took place in Rome (SM@LHC 2024), FNAL (SM@LHC 2023), CERN (SM@LHC 2022), Online (SM@LHC 2021), Zurich (SM@LHC 2019), Berlin (SM@LHC 2018), Amsterdam (SM@LHC 2017), Pittsburgh (SM@LHC 2016), Florence (SM@LHC 2015), Madrid (SM@LHC 2014), Freiburg (SM@LHC 2013), Copenhagen (SM@LHC 2012), Durham (SM@LHC 2011) and London (SM@LHC 2009).

Apart from the topical invited talks the conference will host a poster session during the welcome reception Monday evening. Please register your interest in such contributions at the link to submit abstracts.

11:10 "Experimental results on Energy-Energy Correlators at the LHC"

11:35 "Precise Determination of the Strong Coupling Constant from Dijet Cross Sections up to the Multi-TeV Range"

We determine the value of the strong coupling α_s and study its running over a wide range of scales as probed by the dijet production process at hadron colliders. The analysis is performed using the complete next-to-next-to-leading order (NNLO) predictions in perturbative QCD and is based on dijet data published by ATLAS and CMS at center-of-mass energies of 7, 8, and 13 TeV. From a large subset of these data we infer a value of α_s(m_Z)=0.1178±0.0022 for the strong coupling at the scale of the Z-boson mass m_Z. Complementing the LHC data with dijet cross sections measured at HERA, we extend the range to test the predicted running of the strong coupling towards smaller scales. Our results exhibit excellent agreement with predictions based on the renormalization group equation of QCD. This study represents the a very comprehensive test of the asymptotic
behaviour of QCD, spanning over three orders of magnitude in energy scale from 7GeV up to 7TeV. (Work based on arXiv:2412.21165)
