HERAFitter is an open-source package that provides a framework for the determination of parton distribution functions (PDFs) proton and many different kinds analyses in Quantum Chromodynamics (QCD). It encodes results from wide range experimental measurements lepton–proton deep inelastic scattering proton–proton (proton–antiproton) collisions at hadron colliders. These are complemented with variety theoretical options calculating PDF-dependent cross section predictions corresponding to...
A method to facilitate the consistent inclusion of cross-section measurements based on complex final-states from HERA, TEVATRON and LHC in proton parton density function (PDF) fits has been developed. This can be used increase sensitivity data deviations Standard Model predictions. The stores perturbative coefficients NLO QCD calculations final-state observables measured hadron colliders look-up tables. allows posteriori functions (PDFs), strong coupling, as well a variation renormalisation...
We present the first open-source analysis of parton distribution functions (PDFs) charged pions using xFitter, an QCD fit framework to facilitate PDF extraction and analyses. Our calculations are implemented at next-to-leading order (NLO) APPLgrids generated by MCFM generator. Using currently available Drell-Yan photon production data, we find valence is well constrained; however, considered data not sensitive enough unambiguously determine sea gluon distributions. Fractions momentum carried...

We present the interface between MadGraph5_aMC@NLO, a self-contained program that calculates cross sections up to next-to-leading order accuracy in an automated manner, and APPLgrid, code parametrises such form of look-up tables which can be used for fast computations needed context PDF fits. The main characteristic this interface, we dub aMCfast, is its being fully as well, removes need extract manually process-specific information additional physics processes, case with other...

The calculation of cross-sections at Next-to-Leading order in QCD involves the integration over final state phase space to cancel infra-red divergences.For cross sections for jet observables deep-inelastic scattering or hadron-hadron colliders this requires Monte Carlo generation a large number event weights, and must be repeated any with different choice parton densities within proton factorisation renormalisation scale.This makes full many available density function error sets, iterative...
Recent measurements of the W-boson charge asymmetry and Z-boson production cross sections, performed at Tevatron collider in Run II by D0 CDF collaborations, are studied using HERAFitter framework to assess their impact on proton parton distribution functions (PDFs). The measurements, together with deep-inelastic scattering data from HERA, included a QCD analysis next-to-leading order, compared predictions obtained other PDF sets different groups. Good agreement between theoretical is...

Current waste sorting mechanisms, particularly those relying on manual processes, semi-automated systems, or technologies without Artificial Intelligence (AI) integration, are hindered by inefficiencies, inaccuracies, and limited scalability, reducing their effectiveness in meeting growing management demands. This study introduces a prototype machine that integrates an AI-driven vision system with Programmable Logic Controller (PLC) for high-accuracy automated sorting. The system, powered...

SUMMARY This paper discusses the background and effect of use intense cold to destroy ablate unwanted tissue in obstructive prostate. The equipment methods so far adopted are explained. A review first 100 cases done by our Canadian group from January August 1966 is tabulated. Our experience date indicates that selected this new modality offers a further tool treating prostate gland disease, thereby broadens range safety surgery
