Operation and radiation damage studies of the ATLAS pixel detector / Rossini, L (Milan U. ; INFN, Milan) /ATLAS
The ATLAS pixel detector provides the innermost layers of the InnerDetector tracker. Due to its proximity to the collision region the pixel detector hasbeen exposed to considerable levels of radiation during its operation at the LHC,up to $2-10^{14}n_{eq}/cm^2$. [...]

The upgrade of the Inner Tracking System of the ALICE experiment / Ravasenga, I (INFN, Turin ; Turin Polytechnic) /ALICE
In 2021, for the third run of the CERN Large Hadron Collider(LHC), Pb-Pb collisions will be performed at a centre-of-mass energy per nucleon of 5.5 TeV, with an integrated luminosity of $6×10^{27}cm^{−2}s^{−1}$ and at an unprecedented interaction rate up to 50 kHz. To fulfil the requirements of the ALICE physics program for Run 3, the ALICE experiment at LHC is planning a major upgradeduring the Long Shutdown 2 of LHC in 2019–2020. [...]

Status of the art of the Italian micromegas for the upgrade of the ATLAS detector / Introzzi, G (INFN, Pavia ; Pavia U.) /Atlas
Large-size multilayer resistive micromegas detectors will be employed for the muon spectrometer upgrade of the ATLAS experiment at CERN, the new small wheel project. The status of the art of the micromegas construction in Italy will be reviewed, along with the performance studied on the first full size module..

The novel photon detectors based on MPGD technologies for COMPASS RICH-1 upgrade / Chatterjee, C (INFN, Trieste ; Trieste U.) /COMPASS RICH Group
The RICH-1 detector of the COMPASS experiment at CERN SPShas been upgraded for the 2016 physics run: four MWPC-based photon detectorshave been replaced by newly developed detectors based on MPGD technologies, fora total active area of 1.4 $m^2$. The new detector architecture consists in a hybrid com-bination of two layers of THGEMs, the first acting as a reflective photocathode, anda Micromegas equipped with a pad segmented anode. [...]

Development and deployment of a fast Monte Carlo simulation in LHCb / Siddi, B G (CERN ; INFN, Ferrara) /LHCb
With the steady increase in the precision of flavour physics measure-ments with data from Run 2 of the LHC, the LHCb experiment requires simulateddata samples of ever increasing magnitude to study the detector response in detail.However, relying on an increase of computing resources available for the produc-tion of simulated samples will not suffice to achieve this goal. Therefore, multipleefforts are currently being investigated to reduce the time needed to simulate anevent. [...]

Measurements of $CP$ violation in neutral B mesons at LHCb / Belloli, N (Milan Bicocca U. ; INFN, Milan Bicocca) /LHCb
During 2011 and 2012 the LHCb detector collected data comingfrom proton-proton collision corresponding to an integrated luminosity of 1 $fb^−1$ at a center-of-mass energy of 7 TeV and 2 $fb^−1$ at a center-of-mass energy of 8 TeV,respectively. Using this data sample LHCb can measure with an unprecedentedprecision the parameters associated to the CKM matrix. [...]

Searches for $CP$ violation in beauty baryons at LHCb / Marangotto, Daniele (Milan U. ; INFN, Milan)
The understanding ofCP-violating mechanisms in the baryon sectoris of particular importance in light of the observed matter-antimatter asymmetryin the Universe, but few studies have been performed in baryon decays to date.The searches forCPviolation in beauty baryons performed by the LHCb Col-laboration on LHC Run I data are reported, including the first evidence for $CP$ violation in a baryon decay, $\Lambda_b^0\rightarrow p\pi^-\pi^+\pi^-$. Prospects for LHC Run II are also outlined..
