Covid-19 and Worker Issues: Lessons From a University-based Ad-Hoc Network.

The Covid-19 pandemic has made clear the central role of the workplace in public health. Workers and working families have been particularly impacted by a public health and economic crisis that has revealed both structural shortcomings and opportunities for future preparedness. In response to the pandemic, a group of scholars, labor and anti-poverty advocates, activists, union representatives, frontline workers, and public health professionals gathered to share observations and create a forum for information sharing and collaboration.

Measurements of the [Formula: see text] production cross section in lepton+jets final states in pp collisions at 8 [Formula: see text] and ratio of 8 to 7 [Formula: see text] cross sections.

A measurement of the top quark pair production ([Formula: see text]) cross section in proton-proton collisions at the centre-of-mass energy of 8[Formula: see text] is presented using data collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 19.6[Formula: see text]. This analysis is performed in the [Formula: see text] decay channels with one isolated, high transverse momentum electron or muon and at least four jets, at least one of which is required to be identified as originating from hadronization of a b quark.

Search for Dark Matter and Supersymmetry with a Compressed Mass Spectrum in the Vector Boson Fusion Topology in Proton-Proton Collisions at sqrt[s]=8 TeV.

A first search for pair production of dark matter candidates through vector boson fusion in proton-proton collisions at sqrt[s]=8  TeV is performed with the CMS detector. The vector boson fusion topology enhances missing transverse momentum, providing a way to probe supersymmetry, even in the case of a compressed mass spectrum. The data sample corresponds to an integrated luminosity of 18.

Measurements of the associated production of a Z boson and b jets in pp collisions at .

Measurements of the associated production of a boson with at least one jet originating from a b quark in proton-proton collisions at are presented. Differential cross sections are measured with data collected by the CMS experiment corresponding to an integrated luminosity of 19.8 .
