Abstract: The European Strategy for Particle Physics identified an high-energy e+e- collider studying the Higgs boson as the next priority collider project. The different proposals to realize such a collider all reach a similar performance on the core Higgs program at 250 GeV, albeit with different choices of luminosity and polarisation - but they differ in capabilities at lower and higher energies. This talk will review the physics capabilities of future e+e- linear colliders in the Higgs sector and beyond, with a specific emphasis illuminating the interplay of the top-level beam parameters luminosity, energy and polarisation.

Abstract : Particle cascades originating from quarks and gluons decays (jets) are omnipresent in proton-proton collisions at the LHC. The identification of jet flavours is essential for many physics searches at the ATLAS experiment. This is achieved using machine learning algorithms (taggers) which combine tracks and jets information to determine the flavour of the jets ($b$-jets, $c$-jets and light jets). These taggers are trained with simulated Monte Carlo events and, due to simulations imperfections, their performance need to be measured in data in order to extract correction factors for the simulation predictions. ATLAS developed a set of calibration techniques for different jets flavours to correct, then the correction factors need to be re-derived every time a new tagger is deployed. Automating the calibration workflow significantly accelerates the calibration cycle and makes it less prone to manual mistakes. We present the first automated calibration framework in ATLAS using REANA platform. The results are compared with the official results using 36.2 $\mathrm{fb}^{-1}$ of 13 TeV collisions data from ATLAS, and a new set of calibration results with a customised setup is also included. The same method can be applied in other contexts to reduce the amount of time and resources needed to achieve the scientific goals.
