/ Garzia, I (INFN, Ferrara ; Ferrara U.) ; Alexeev, M (INFN, Turin) ; Amoroso, A (INFN, Turin ; Turin U.) ; Baldini Ferroli, R (Frascati ; Beijing, Inst. High Energy Phys.) ; Bertani, M (Frascati) ; Bettoni, D (INFN, Ferrara) ; Bianchi, F (INFN, Turin ; Turin U.) ; Calcaterra, A (Frascati) ; Canale, N (Ferrara U.) ; Capodiferro, M (Frascati ; INFN, Rome) et al.
Gas detector development is one of the pillars of the research in fundamental physics. Since several years, a new concept of detectors, called Micro Pattern Gas Detector (MPGD), allowed to overcome several problems related to other types of commonly used detectors, like drift chamber and micro strips detectors, reducing the rate of discharges and providing better radiation tolerance.

On the space resolution of the μ-RWELL

In MPGD detectors evaluation of the space resolution with the charge centroid (CC) method provides large uncertainty when the impinging particle is not perpendicular to the readout plane. An improvement of the position reconstruction, and thus of the space resolution, is represented by the $\mu$TPC algorithm. [...]

TetraBall: A single-moderator neutron spectrometer for HL-LHC
/ Bedogni, R (Frascati) ; Costa, M (INFN, Turin ; Turin U.) ; Durisi, E (INFN, Turin ; Turin U.) ; Mafucci, E (INFN, Turin ; Turin U.) ; Monti, V (INFN, Turin ; Turin U.) ; Caballero Pacheco, M A (Frascati) ; Castro Campoy, A I (Frascati) ; Dashdondog, D (Frascati) ; Russo, L (Frascati) ; Pietropaolo, A (Frascati ; ENEA, Frascati) et al.
This contribution presents a novel single-moderator neutron spectrometer, named “TetraBall”, developed at INFN and optimized for characterizing the neutron field in the CMS experimental cavern. The TetraBall condenses the functionality of several Bonner Spheres (BS) in a single moderator and it is equipped with 42 SiC radiation-hard detectors organized in a tetrahedral geometry designed to be insensitive to incident gammas and charged particles.

Analytic integration of soft and collinear radiation in factorised QCD cross sections at NNLO
/ Magnea, Lorenzo (CERN ; Turin U. ; INFN, Turin) ; Pelliccioli, Giovanni (Wurzburg U.) ; Signorile-Signorile, Chiara (Turin U. ; INFN, Turin ; KIT, Karlsruhe, Dept. Phys.) ; Torrielli, Paolo (Turin U. ; INFN, Turin) ; Uccirati, Sandro (Turin U. ; INFN, Turin)
Within the framework of local analytic sector subtraction, we present the full analytic integration of double-real and real-virtual local infrared counterterms that enter NNLO QCD computations with any number of massless final-state partons. We show that a careful choice of phase-space mappings leads to simple analytic results, including non-singular terms, that can be obtained with conventional integration techniques..
