Parton distributions with QED corrections
read the original abstract
We present a set of parton distribution functions (PDFs), based on the NNPDF2.3 set, which includes a photon PDF, and QED contributions to parton evolution. We describe the implementation of the combined QCD+QED evolution in the NNPDF framework. We then provide a first determination of the full set of PDFs based on deep-inelastic scattering data and LHC data for W and Z/gamma* Drell-Yan production, using leading-order QED and NLO or NNLO QCD. We compare the ensuing NNPDF2.3QED PDF set to the older MRST2004QED set. We perform a preliminary investigation of the phenomenological implications of NNPDF2.3QED: specifically, photon-induced corrections to direct photon production at HERA, and high-mass dilepton and W pair production at the LHC.

Machine learning study on single production of a singlet vectorlike lepton at the Large Hadron Collider
With XGBoost at 14 TeV and 3000 fb⁻¹, 2σ exclusion of a tau-mixing singlet vectorlike lepton can reach ~500 GeV (3-lepton) and ~405 GeV (4-lepton) if systematics are negligible.

Octet scalars shaping LHC distributions in 4-jet final states

Search for Dark Matter in 2HDMS at LHC and future Lepton Colliders
Benchmarks in the 2HDMS model with light to heavy dark matter masses are identified under all constraints and shown to have better discovery prospects at future lepton colliders than at the HL-LHC via cut-and-count analyses.
