Colibri: A new tool for fast-flying PDF fits
Mark N. Costantini, Luca Mantani, James M. Moore +2
We present Colibri, an open-source Python code that provides a general and flexible tool for PDF fits. The code is built so that users can implement their own PDF model, and use th…
A linear PDF model for Bayesian inference
Mark N. Costantini, Luca Mantani, James M. Moore +1
A robust uncertainty estimate in global analyses of Parton Distribution Functions (PDFs) is essential at the Large Hadron Collider (LHC), especially in view of the high-precision d…
A critical study of the Monte Carlo replica method
Mark N. Costantini, Maeve Madigan, Luca Mantani +1
We present a detailed mathematical study of the Monte Carlo replica method as applied in the global fitting literature from the high-energy physics theory community. For the first…
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…
Hide and seek: how PDFs can conceal New Physics
Elie Hammou, Zahari Kassabov, Maeve Madigan +5
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…
The top quark legacy of the LHC Run II for PDF and SMEFT analyses
Zahari Kassabov, Maeve Madigan, Luca Mantani +4
We assess the impact of top quark production at the LHC on global analyses of parton distributions (PDFs) and of Wilson coefficients in the SMEFT, both separately and in the framew…
The dark side of the proton
Matthew McCullough, James Moore, Maria Ubiali
We study the sensitivity of the High-Luminosity LHC to a light baryonic dark photon B, primarily coupled to quarks, as a constituent of the proton. This is achieved by allowing for…
Parton distributions in the SMEFT from high-energy Drell-Yan tails
Maeve Madigan, James Moore
We present a study of the interplay between PDF and EFT effects in high-mass Drell-Yan at the LHC. We quantify the impact of a consistent joint determination of the PDFs and Wilson…
Parton distributions in the SMEFT from high-energy Drell-Yan tails
Admir Greljo, Shayan Iranipour, Zahari Kassabov +5
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 th…
