Symbolic regression for precision LHC physics
Manuel Morales-Alvarado, Daniel Conde, Josh Bendavid +2
We study the potential of symbolic regression (SR) to derive compact and precise analytic expressions that can improve the accuracy and simplicity of phenomenological analyses at t…
Combination of aNLO PDFs and implications for Higgs production cross-sections at the LHC
Thomas Cridge, Lucian A. Harland-Lang, Jamie McGowan +14
We discuss how the two existing approximate NLO (aNLO) sets of parton distributions (PDFs) from the MSHT20 and NNPDF4.0 series can be combined for LHC phenomenology, both i…
Unravelling New Physics Signals at the HL-LHC with Low-Energy Constraints
Elie Hammou, Maria Ubiali
Recent studies suggest that global fits of Parton Distribution Functions (PDFs) might inadvertently 'fit away' signs of new physics in the high-energy tails of the distributions me…
Parton Distribution Functions and Their Impact on Precision of the Current Theory Calculations
Maria Ubiali
The unprecedented precision of experimental measurements at the Large Hadron Collider (LHC) and the increased statistics that will be reached in the High-Luminosity phase of the LH…
Di-Higgs production via Axion-Like Particles
Fabian Esser, Maeve Madigan, Alexandre Salas-Bernardez +2
Due to the pseudo-scalar nature of the axion-like particle (ALP), the CP- conserving production of two Higgs bosons via the ALP necessarily involves an additional Z or boson. W…
SIMUnet: an open-source tool for simultaneous global fits of EFT Wilson coefficients and PDFs
Mark N. Costantini, Elie Hammou, Zahari Kassabov +5
We present the open-source SIMUnet code, designed to fit Standard Model Effective Field Theory (SMEFT) Wilson coefficient alongside Parton Distribution Functions (PDFs) of the prot…
