In this work we illustrate the POWHEG BOX, a general computer code framework for implementing NLO calculations in shower Monte Carlo programs according to method. Aim of is provide an illustration needed theoretical ingredients, view how organized and description what user should order use it.
In response to the 2013 Update of European Strategy for Particle Physics, Future Circular Collider (FCC) study was launched, as an international collaboration hosted by CERN. This covers a highest-luminosity high-energy lepton collider (FCC-ee) and energy-frontier hadron (FCC-hh), which could, successively, be installed in same 100 km tunnel. The scientific capabilities integrated FCC programme would serve worldwide community throughout 21st century. also investigates LHC energy upgrade,...
