The LHC has been recently shut down and therewith its first period ofrunning brought to an end. The highlight of the past three years is thediscovery of the Higgs boson, thus completing the experimental confirmationof the Standard Model (SM) in all its building blocks and structure. Adetailed experimental study of the couplings of the Higgs boson to itselfand to the other SM particles is a future goal of the second phase of theLHC and of future accelerators, but from measurements performed so far, itseems that the SM predictions are confirmed at the current level ofprecision. This great success of the LHC and of its experiments has itscounterpart in the lack of any sign of new physics -- not that theexperiments are to blame for this, since they have worked even better thanexpected. Nature has not fulfilled our (presumably too naive) expectationsand presents us with the problem of thinking with a fresh mind aboutpossible extensions of the SM to higher energy scales.There are however a few puzzles which are left unexplained. One of the mostresistant to theoretical and experimental scrutiny remains that of the$(g-2)$ of the muon. While ten years ago the discrepancy betweenmeasurement and SM prediction has been called a ``harbinger of newphysics'', the increased bounds on all beyond-the-Standard-Model (BSM)particles makes the same discrepancy a true puzzle. For example, the``natural'' explanation of the discrepancy within a supersymmetric (SUSY)extension of the SM has now become very problematic because the bounds onthe SUSY particles -- especially those of the first and second generation,which are those needed to explain the $(g-2)_\mu$ puzzle -- are now toohigh. Some of the other puzzles have been generated at the LHC itself, like themeasurement of CP violation in $D$-meson decays, which seems to be higherthan what the SM predicts -- here a cautious formulation of the puzzle(``seems'') is mandatory, because of the difficulty in making a reliable SMprediction. A difficulty which at present we do not even know how to solvein the near or medium-term future.In summary, after the first running phase of the LHC the confirmations ofthe SM have increased both in precision and in number. The fundamentalscalar assumed to be responsible for electroweak symmetry breaking has beendiscovered and the flavour and CP violations observed are all compatiblewith the SM. The possibility that the SM is valid up to a scale much higherthan the TeV, despite naturalness arguments, has now to be considered moreseriously. In any case, we will not have new insights on this fundamentalquestion for the coming three years.The current situation makes it even more urgent to continue to work onreducing hadronic uncertainties in observables where there is an apparentdiscrepancy between measurement and SM prediction which is not yet fullyunderstood. This will be the main goal of this project.
