I will discuss the GENEVA Monte Carlo framework, that allows to obtain predictions for underlying-event sensitive measurements in Drell-Yan production using PYTHIA8's MPI model, in conjunction with fully-differential NNLO calculation, NNLL' resummation for the 0-jet resolution variable (beam thrust), and NLL resummation for the $1$-jet resolution variable. I will present results for...
APFEL is a numerical code specialized for PDF fits that provides a
fast and accurate solution of the DGLAP equations. In addition to PDF
evolution, APFEL also provides a module that computes DIS cross
sections in several mass schemes. In this contribution I will present
the most recent and relevant developments carried out in APFEL. They
include: the computation of the time-like evolution,...
We present the latest versions of TMDlib and
TMDplotter. Basic features of TMDplotter include plotting as a function of the
momentum fraction, the transverse momentum, or the evolution scale, as well as
integration of TMDs and comparison to sets from LHAPDF. Latest improvements
include a upload of new sets from the web interface and the plotting of the
uncertainties. Luminosity for collinear...
We present the xFitter project (former HERAFitter) which provides a unique open-source software framework for the determination of the proton's PDFs and for the interpretation of the physics analyses in the context of Quantum Chromodynamics.
We highlight the new xFitter software release which includes many new
features and additions, e.g. the possibility of the inclusion of photon...
The xFitter (former HERAFitter) is an open-source package that provides
a framework for the determination of the proton PDFs and covers a large
number of the existing methods and schemes for PDF determination.
xFitter also provides facilities to use diverse methodologies alternative to the
standard collinear formalism, as provided by DGLAP evolution equations.
The...
