 The TOFHIR2 readout ASIC of the CMS Barrel MIP Timing Detector / Joao Varela for the TOFHIR team The CMS Detector will be upgraded for the HL-LHC to include a MIP Timing Detector (MTD). The MTD will consist of barrel and endcap timing layers, BTL and ETL respectively, providing precision timing of charged particles. [...] CMS-CR-2021-001.- Geneva : CERN, 2021 - 8 p.

 Cwebs beyond three loops in multiparton amplitudes / Agarwal, Neelima (Chaitanya Bharathi Institute of Technology, Hyderabad) ; Magnea, Lorenzo (CERN ; Turin U. ; INFN, Turin) ; Pal, Sourav (Indian Inst. Tech., Hyderabad) ; Tripathi, Anurag (Indian Inst. Tech., Hyderabad) Correlators of Wilson-line operators in non-abelian gauge theories are known to exponentiate, and their logarithms can be organised in terms of collections of Feynman diagrams called webs.
