The solar wind is a supersonic and super-alfvenic flow of plasma that propagates in space up to the Earth and throughout the heliosphere reaching speeds of about 400 􀀀 800 km s􀀀1. It permeates the heliosphere and is ...

In this thesis the measurements of differential cross sections of top quark pair production in association with jets are presented. Data collected by the ATLAS experiment at the LHC during the 2015 corresponding to an ...

In this thesis, measurements of the differential cross-section for top-quark pair production in proton-proton collisions at a centre-of-mass energy of ps = 13 TeV are presented. The measurements are performed using data ...

The local emergency of Beltrami ows is a fundamental characteristic of the uid turbulence dynamics (Navier-Stokes equations), where the formation of singularities starting from smooth initial data, i.e. the breakdown ...

Since ancient times human activities have significantly altered the natural global Mercury (Hg) cycle through emissions to the environment. Hg is a global pollutant since its predominant atmospheric form, elemental Hg, ...

The study of the production of prompt photons in association with hadronic jets provides a test of perturbative Quantum Chromodynamics and gives information on the proton parton distribution functions. The colorless ...

In the last decades, the global ecosystem has been increasingly threatened by problems, like as, climate change and air pollution, due to the increasing of pollutant emissions that are altering the balance of atmospheric gases. ...

La sica dei sistemi di molti corpi interagenti e un campo di ricerca molto attivo a causa dei sorprendenti progressi nella realizzazione, controllo e misurazione di tali sistemi, e dell'esistenza di problemi fondamentali ...

In the field of nanotechnologies the Two-Photons Direct Laser Writing (TP-DLW) is the most advanced optical technique for creating arbitrarily complex 3D structures in organic resists, featuring details down to 50 nm, well ...
