This page contains information about the various research software development projects in which I am involved.

  • Precision determination of the small-x gluon from LHC charm production. The fits based on the NNPDF3.0 global analysis supplemented with LHCb data at 5 TeV, 7 TeV and 13 TeV, leading to an improved determination of the small-x gluon PDF, presented in this work, can be used for calculations in neutrino astronomy and cosmic ray physics, Monte Carlo event generators and for studies at future high-energy colliders. These fits are publicly available in the LHAPDF6 format, for the N5+N7+N13 combination and for the N7+R13/5 combination
  • APFEL online Graphical User Interface.  A web server that provides easy online access to the GUI of the APFEL parton evolution program,  and its flexible plotting functionalities that allow to perform a wide range of comparisons between different PDF sets at the level of parton distributions, parton luminosities and DIS structure functions.
  • NNPDF parton distributions. I am one of the members of the NNPDF Collaboration whose main goal is to develop sets of parton distribution functions (PDFs), a crucial ingredient for LHC phenomenology. The webpage of the collaboration is hosted in HepForge, and the various NNPDF sets are available from the LHAPDF library. Stand-alone drivers for the NNPDF sets and the corresponding tutorial can be found here. A Mathematica interface for NNPDF sets is also available.
  • PromptNuFlux.  This code provides a state-of-the-art calculation of the prompt atmospheric neutrino fluxes for a wide range of neutrino energies and various models for the cosmic ray flux, including theoretical uncertainties.
  • aMCfast. The availability of fast interfaces to NLO and NLO+parton shower computations is essential to include hadron collider data into global PDF analysis. aMCfast, also hosted in HepForge, is a fast interface to Madgraph5_aMCatNLO program based on the APPLgrid framework, which provides an automation of fast NLO and NLO+PS interfaces for arbitrary collider processes, already for QCD corrections and soon for NLO EWK corrections as well.
  • APFEL, A Parton distribution Function Evolution Library with QED corrections, is a PDF evolution program which provides predictions up to NNLO in the QCD coupling and up to LO in the QED coupling. APFEL is available via the HepForge repository. A Graphical User Interface is also available with a variety of plotting tools for PDFs and parton luminosities
  • SMPDF. A web server that provides user-friendly, interactive access to the SM-PDF package for the construction of specialized PDF sets taillored for specific LHC applications. This tool also includes the mc2hessian code, that generates Hessian sets starting from an input PDF set in the Monte Carlo representation.
  • HOPPET, a Higher Order Perturbative Parton Evolution Toolkit, is a Fortran95 package capable of performing PDF evolution up to NNLO QCD and to perform a variety of related operations on parton distributions. It is available from the HepForge repository.
  • JetQuality is an on-line tool which allows the user to check the performance of a wide variety of jet clustering definitions for kinematic reconstructions at hadron colliders
  • EPS09MC is the Monte Carlo version of the widely used EPS09 nuclear parton distribution functions. They can be used to quantify the constraints on nuclear PDFS from new data in nuclear collisions. The grid files and driver code are available from the HOTLHC webpage.
  • FONLLdis is a code that implements the FONLL general-mass heavy quark variable-flavor number scheme for Deep-Inelastic Scattering structure functions up to NNLO. It is publicly available here. This is the heavy quark scheme that is used in the global PDF fits of the NNPDF collaboration.
