Fine tuning of track impact parameter resolution of the DELPHI detector

The fine tuning of the charged track impact parameter resolution for data and simulation in the DELPHI detector at LEP is described. This tuning was implemented in the software for the tagging of $B$ hadrons and has been applied in many precise measurements

Higgs boson couplings: Measurements and theoretical interpretation

This report will review the Higgs boson properties: the mass, the total width and the couplings to fermions and bosons. The measurements have been performed with the data collected in 2011 and 2012 at the LHC accelerator at CERN by the ATLAS and CMS experiments. Theoretical frameworks to search for new physics are also introduced and discussed.Comment: 67 pages, 23 figure

First results of the two square meters multilayer glass composite mirror design proposed for the Cherenkov Telescope Array developed at INFN

The Cherenkov Telescope Array (CTA) is a future ground-based gamma-ray astronomy detector that will consist of more than 100 Imaging Atmospheric Cherenkov Telescopes of different sizes. The total reflective surface of roughly 10 000 m$^2$ requires unprecedented technological efforts towards a cost-efficient production of light-weight and reliable mirror substrates at high production rate. We report on a new mirror concept proposed for CTA developed by INFN, which is based on the replication from a spherical convex mold under low pressure. The mirror substrate is an open structure design made by thin glass layers at the mirror's front and rear interspaced by steel cylinders. A first series of nominal size mirrors has been produced, for which we discuss the optical properties in terms of radius of curvature and focusing power

Emerging work patterns and different territorial contexts: trends for the coworking sector in pandemic recovery

Objectives: The paper aims to explore and unpack the complexity of coworking's users and supply (i.e. coworking spaces), based on the recent trends caused by Covid19. It is discussed whether and how coworking's environment increases its diversification in terms of users and the spatial and policy implications linked to this shift. Methodology: The study embraces a qualitative approach exploring the existing literature on the emerging dynamics in the field of work, moving from an overview of recent trends across Europe based on existing international surveys. Results: New possible scenarios may be based on different forms of proximity, not just in the dense metropolitan cores, but also in other types of territories, where the population may decide to selectively re-distribute, and the question will be how to supply all these areas with effective, efficient and equal opportunities in terms of jobs and services. The study highlights the diffusion of shared workspaces in different forms: traditional coworking spaces catering for freelancers and knowledge workers, but also workspaces in which employees from large organisations (public and private) will spend part of their working week, hybrid spaces based on peculiar combinations of locally required services (related to both jobs and care), third-spaces based on some form of everyday recreational activities, and many others. Limits and implications: The pandemic is still ongoing and, since the paper focuses on the review of existing literature and surveys in a changing context, its main limitation is the ability to collect verifiable and up-to-date data. Originality: The paper's uniqueness lies in the prefiguration of a range of development directions concerning the relationship between work practices and collaborative spaces in different territories, exploring how local and diffused dynamics might be the opportunity for a potential transformation of work patterns
