Searches for non-resonant HH production at CMS / Cappati, Alessandra (INFN, Turin ; Turin U.) /CMS Collaboration
The most recent results from searches for non-resonant production of Higgs boson pairs~(HH) at CMS are presented. Four final states have been studied, with data collected at $\sqrt{s}=13\,\mathrm{TeV}$ in 2016, corresponding to an integrated luminosity of $35.9\,\mathrm{fb}^{-1}$. [...]

The CMS Muon System performance during the LHC Run-2 / Pozzobon, Nicola (INFN, Padua ; Padua U.) /CMS Collaboration
A highly performing muon system has been fundamental to achieve many of the physics results obtained by CMS during the LHC Run-2. The CMS muon spectrometer presently consists of three detector technologies covering different regions of pseudorapidity. [...]

Firmware Upgrade of the CMS Phase-1 Pixel Front-End Controller: Impact on Pixel Operation and DAQ / Modak, Atanu (Kansas State U.) /CMS Collaboration
The Pixel Front-End Controller of the CMS Phase-1 Pixel detector is responsible for programming the front-end chips and distributing the trigger, clock and fast signals to the detector modules. An upgrade of the Pixel FEC firmware was undertaken and was successfully integrated into the online software. [...]

Measurement of the $\eta_c(1S)$ production cross-section in $pp$ collisions at $\sqrt{s} = 13$ TeV
Using a data sample corresponding to an integrated luminosity of $2.0\,fb^{-1}$, collected by the LHCb experiment, the production of the $\eta_c(1S)$ state in proton-proton collisions at a centre-of-mass energy of $\sqrt{s}=13 \text{ TeV}$ is studied in the rapidity range ${2.0 < y < 4.5}$ and in the transverse momentum range ${6.5 < p_{T} < 14.0\text{ GeV}}$.

Study of prompt $D^0$ meson production in $p$Pb at $\sqrt{s_{\mathrm{NN}}}= 8.16$ TeV at LHCb /LHCb Collaboration
The production of prompt $D^0$ mesons in proton-lead collisions in the forward and backward configurations is studied. The data are collected with the LHCb detector at a center-of-mass energy per nucleon pair of $\sqrt{s_{\mathrm{NN}}}= 8.16$ TeV and correspond to an integrated luminosity of $12.2\pm0.3~\mathrm{nb}^{-1}$ ($18.6\pm0.5~\mathrm{nb}^{-1}$) in the forward (backward) configuration.

The DNNLikelihood: enhancing likelihood distribution with Deep Learning / Coccaro, Andrea ; Pierini, Maurizio ; Silvestrini, Luca ; Torre, Riccardo
We introduce the DNNLikelihood, a novel framework to easily encode, through Deep Neural Networks (DNN), the full experimental information contained in complicated likelihood functions (LFs). [...]
