Lepton flavour universality tests in B decays at LHCb / Atzeni, Michele (Zurich U.) /LHCb
The universality of the electroweak boson couplings to the different lepton flavours is a fundamental property of the Standard Model that is expected to be violated in a variety of new physics scenarios. A review of recent results obtained by the LHCb collaboration in semileptonic decays involving both charged and neutral currents is presented. [...]

Measurements of $CP$ Violation in the b and c hadrons decays at the LHC / Krupa, Wojciech (AGH-UST, Cracow) /LHCb
Measurements of Charge-Parity violating observables in the decays of $b$ and $c$ hadrons are powerful probes to search for Physics beyond the Standard Model. The recent results on CP violation of both $b$ and $c$ hadrons measured at the LHC (LHCb, ATLAS and CMS experiments) are reviewed in this paper. [...]

Recent QCD results from the NA48/2 experiment / Anzivino, Giuseppina (INFN, Perugia ; Perugia U.) /NA48/2
The NA48/2 experiment collected data in 2003 and 2004 with the main purpose to study direct CP violation in charged kaons decaying in three pions. Thanks to the huge statistics collected, other studies are also possible. [...]

New proposal for low-emittance muon collider / Antonelli, Mario (Frascati) ; Blanco-Garcia, O R (Frascati) ; Boscolo, M (Frascati) ; Guiducci, S (Frascati) ; Ricci, M (Frascati) ; Rotondo, M (Frascati) ; Lorenzon, A (Padua U. ; INFN, Padua) ; Lucchesi, D (Padua U. ; INFN, Padua) ; Rossini, S (Padua U. ; INFN, Padua) ; Vanini, S (Padua U. ; INFN, Padua) et al.
These proceedings introduce a new proposal for a low-emittancemuon collider. A low-emittance muon beam is obtained from the process e$^+$e$^-\rightarrow\mu^+\mu^-$ with positrons at the threshold energy of 45 GeV. [...]

Top pair production cross sections at LHCb / Lucchesi, Donatella (Pavia U. ; INFN, Pavia) /LHCb
The production and decay properties of the top-quark are sensitive to new physics in several scenarios beyond the Standard Model. LHCb is the only experiment where the top-quark can be studied in the forward region exploiting, therefore, production mechanisms different from ATLAS and CMS experiments. [...]

Top quark pair production cross sections at CMS / Gonzalez Fernandez, Juan Rodrigo (Oviedo U.) /CMS
A summary of the latest results on inclusive and differential $\mathrm{t}\bar{\mathrm{t}}$ cross sections by CMS is presented. Several new differential cross section measurements have been performed by CMS using an amount of 35.9 fb$^{-1}$ of data collected in 2016. [...]

Luminosity Measurements in ATLAS and CMS during pp data taking at LHC / Valentinetti, Sara (Bologna U. ; INFN, Bologna) /ATLAS ; CMS
A precise measurement of luminosity is a key component of both the ATLAS and CMS physics programmes at LHC: its uncertainty is one of the dominant systematics for both Standard Model cross section measurements and enters new physics searches. The different strategies used by the two collaborations to assess the luminosity and the methods to absolutely calibrate it are here described, together with the dominant systematic uncertainties.

A Brief Discussion on the Performance of the MoEDAL and the LHCf Experiments / Santra, Arka (Valencia U., IFIC) /MoEDAL ; LHCf
The Monopole and Exotics Detector at the LHC (MoEDAL) experiment is an experiment dedicated to searching for beyond standard model (BSM) particles like magnetic monopoles, highly ionizing particles and slow-moving supersymmetric particles. In many ways, this detector complements the BSM searches of ATLAS and CMS. [...]

Flavour Tagging in the LHCb experiment / Fazzini, Davide (INFN, Milan Bicocca ; Milan U.) /LHCb
The $C\!P$ violation measurements represent one of the key topic covered by the LHCb collaboration.The time-dependent $C\!P$ violation measurements requires the knowledge of the flavour at production of the $B$ signal candidate, thus the flavour tagging tool represents a fundamental ingredient for this kind of analyses. In this contribution the most recent results in the flavour tagging achieved at the LHCb experiment are highlighted..

Real-time physics, alignment and reconstruction in the LHCb trigger / Pearce, Alex (CERN) /LHCb
Since 2015, the LHCb experiment has employed an exclusively-real-time analysis strategy for a large fraction of its physics programme. Full physics analyses are performed directly on the objects reconstructed in the final stage of the software trigger, negating the need for subsequent offline reconstruction and reducing the output event size, without a loss of performance.
