Construction and test of the SM1 type Micromegas chambers for the upgrade of the ATLAS forward muon spectrometer
/ Agarwala, J (Pavia U.) ; Alviggi, M G (Naples U. ; INFN, Naples) ; Antonelli, M (Frascati) ; Anulli, F (INFN, Rome ; Rome U.) ; Arcangeletti, C (Frascati) ; Auricchio, S (Naples U. ; INFN, Naples) ; Bagnaia, P (INFN, Rome ; Rome U.) ; Bariani, S (Pavia U.) ; Baroncelli, A (Rome III U. ; INFN, Rome3) ; Bashta, I (Rome III U. ; INFN, Rome3) et al.
Large-size Resistive Micromegas have been chosen for the upgrade of the forward muon spectrometer of the ATLAS experiment, the New Small Wheel project. These chambers, together with small-strip Thin Gap Chambers (sTGC), allow reconstruction of high-momentum muon tracks in a high-radiation environment and provide a robust low-threshold single-muon trigger.

Evidence for the charge asymmetry in $pp \rightarrow t\bar{t}$ production at $\sqrt{s}= 13$ TeV with the ATLAS detector
/ ATLAS Collaboration
Inclusive and differential measurements of the top-antitop ($t\bar{t}$) charge asymmetry $A_\text{C}^{t\bar{t}}$ and the leptonic asymmetry $A_\text{C}^{\ell\bar{\ell}}$ are presented in proton-proton collisions at $\sqrt{s} = 13$ TeV recorded by the ATLAS experiment at the CERN Large Hadron Collider. The measurement uses the complete Run 2 dataset, corresponding to an integrated luminosity of 139 fb$^{-1}$, combines data in the single-lepton and dilepton channels, and employs reconstruction techniques adapted to both the resolved and boosted topologies.

Performance of Small-Pad Resistive Micromegas for operation under high particle flow
/ Alviggi, M G (INFN, Naples ; Naples U.) ; Camerlingo, M T (INFN, Rome3 ; Rome III U.) ; Canale, V (INFN, Naples ; Naples U.) ; Della Pietra, M (INFN, Naples ; Naples U.) ; Di Donato, C (INFN, Naples ; Naples U.) ; Iengo, P (CERN) ; Iodice, M (INFN, Rome3) ; Petrucci, F (INFN, Rome3 ; Rome III U.) ; Sekhniaidze, G (INFN, Naples)
Motivated mainly by future upgrades at high-luminosity LHC (HL-LHC) and detectors at future accelerators, most of the HEP R&D; collaborations are focusing on the design of new particle detectors for operation under high particle flow. In the field of Micro-Pattern-Gaseous-Detectors, were designed the small-pad resistive Micromegas prototypes, to overcome the limitations of current resistive strip Micromegas chambers. [...]

Small-pad Resistive Micromegas for Operation at Very High Rates
/ Iengo, Paolo (CERN) ; Alviggi, M G (U. Naples (main) ; INFN, Naples) ; Camerlingo, M T (U. Naples (main) ; INFN, Naples) ; Canale, V (INFN, Naples ; U.

Naples (main)) ; Biglietti, M (INFN, Rome3) ; Iodice, M (INFN, Rome3) ; Petrucci, F (Rome III U. ; INFN, Rome3) et al.
Resistive Micromegas detectors have proved to be suitable for precision tracking in dense particle rate environment up to few kHz/cm$^2$. Rate capability up to few MHz/cm$^2$ and low occupancy can be achieved by using few mm$^2$ readout pads. [...]
