Higgs boson measurements at the LHC

Measurements of the Higgs boson production and decay performed at the Large Hadron Collider by the ATLAS and CMS experiments are reviewed. These measurements are based on proton-proton collision data at $\sqrt{s}$=~13~TeV, corresponding to integrated luminosities ranging from 35 to 80~fb$^{-1}$. With these datasets, the associated production of the Higgs boson with a $t\bar{t}$ pair is observed and the decay of the Higgs boson to $b\bar{b}$ pairs is established. Measurements involving leptonic and bosonic final states are described. The combined constraints on the Higgs boson coupling properties are summarized.

Performances of the NA48 Liquid Krypton calorimeter

The NA48 experiments aims at a precise measurement of direct CP violation in the neutral Kaon system. This puts stringent requirements on the electromagnetic calorimeter used to detect photons of average energy 25 GeV. The choice of NA48 is a quasi homogeneous Liquid Krypton calorimeter with fast readout. The operation of this device and the performances achieved are described.
