(Lyon U. ; CERN ; Lyon, Ecole Normale Superieure) ; Martinez Santos, D. (Santiago de Compostela U., IGFAE) ; Neshatpour, S. (IPM, Tehran)
The well-known problem of the unknown power corrections within QCD improved factorisation leaves the interpretation of the so-called LHCb anomalies in the angular observables of B-->K* mu+ mu- as an open problem. [...]

Topics in Higgs Physics / Ellis, John (King's Coll. London ; CERN)
These lecture notes review the theoretical background to the Higgs boson, provide an introduction to its phenomenology, and describe the experimental tests that lead us to think that "beyond any reasonable doubt, it is a Higgs boson". [...]

Hypermagnetic knots and gravitational radiation at intermediate frequencies / Giovannini, Massimo (CERN ; INFN, Milan Bicocca)
The maximally gyrotropic configurations of the hypermagnetic field at the electroweak epoch can induce a stochastic background of relic gravitational waves with comoving frequencies ranging from the $\mu$Hz to the kHz. [...]

QED Corrections to Hadronic Observables / Patella, Agostino (CERN ; Plymouth U., Math. Stat. Dept.)
When aiming at the percent precision in hadronic quantities calculated by means of lattice simulations, isospin breaking effects become relevant. These are of two kinds: up/down mass splitting and electromagnetic corrections. [...]

Aspects of Berry phase in QFT / Baggio, Marco (Leuven U.) ; Niarchos, Vasilis (Durham U., Dept. of Math. ; Durham U., CPT) ; Papadodimas, Kyriakos (CERN ; U. Groningen, VSI)
When continuous parameters in a QFT are varied adiabatically, quantum states typically undergo mixing---a phenomenon characterized by the Berry phase. [...]
