  1. 601. The HL-LHC: Strategies for beam optics commissioning

    Talk

    Beam optics control in the HL-LHC will present significant challenges, relating to the extremely low-$\beta^*$ in the two main experiments: ATLAS and CMS. The luminosity delivered to the experiments during the first several hours of HL-LHC fills will be kept constant via $\beta^*$-levelling. Such an extensive optimisation will require the commissioning of a large number of optical...

    Following the successful initial phase of the Gamma Factory (GF)
    R&D studies—showing that atomic beams can be efficiently produced
    and accelerated in the CERN rings up to the top LHC energy—the GF

    experiment to study collisions of the laser photons with
    partially stripped ions at the SPS. Following the...

    11. Accelerator: Physics, Performance, and R&D for Future Facilities
    Talk

    Upgrading the SuperKEKB e+e- collider with a polarized e- beam is under consideration as it enables a new program of precision electroweak and other physics at 10.6 GeV, thereby opening exciting new windows in search of new physics. Measurements of left-right asymmetries ($A_{LR}$) of e+e- transitions to pairs of muons, c- and b-quarks would yield substantial improvements to the determinations...

  5. 865. Circular vs linear e+e- colliders, another story of complementarity

    Talk

    The physics program proposed by circular and linear e+e− colliders at the electroweak and TeV scale exhibits considerable complementarity. This could be exploited on a world-wide scale if both a large circular and a linear infrastructures were available. A possible implementation of such a complementary program is shown.

    11. Accelerator: Physics, Performance, and R&D for Future Facilities
    Talk

    To exploit properly the precision physics program at the FCC-ee, the theoretical precision tag on the respective luminosity will need to be improved from the 0.054 % (0.061%) results at LEP to 0.01%, where the former (latter) LEP result has (does not have) the pairs correction. We present an overview of the roads one may take to reach the required 0.01 % precision tag at the FCC-ee and we...

    Talk

    Muon colliders have the potential to carry the search for new phenomena to energies well beyond the reach of the LHC in the same or smaller footprint. Muon beams may be created through the decay of pions produced in the interaction of a proton beam with a target. To produce a high-brightness beam from such a source requires that the beam be cooled. Ionization cooling is the novel technique by...

    In the framework of the European Strategy Update on Particle Physics, the working group appointed to review the Muon Colliders has become the de facto seed of an on-going international effort. A muon collider, if demonstrated to be feasible, is a unique discovery machine and the best tool to fully study the Higgs potential, since it can offer collisions of point-like particles at very high...

    A Muon Collider represents a very interesting possibility for a future machine to explore the energy frontier in particle physics.
    However, to reach the needed luminosity, beam intensities of the order of 10^9-11 muons per bunch are needed. In this context, the beam Induced Background must be taken into account for its effects on the magnets and on the detector.
    Several optimisations can be...

    The Mu2e experiment, currently under construction at Fermilab, will search for coherent neutrinoless muon to electron conversion, extending the sensitivity of searches for charged lepton flavor violation by four orders of magnitude in 3-5 years of data-taking. This improved sensitivity is made possible by using a pulsed beam structure that is optimized for reducing prompt backgrounds when...

    Bent crystals are a powerful mean for ultrarelativistic particles steering, achieving deflection equivalent to hundreds-tesla magnetic dipole in compact and zero-energy consumption devices. Currently, bent crystals are a candidate for the upgrade of LHC ion collimation. Novel experimental setups are being proposed, especially in the field of spin precession. Indeed, the unparallel steering...

    The SuperKEKB electron-positron collider has been commissioned at KEK to study a new physics in the B-meson decays. In order to accomplish this purpose, the luminosity of 40 times of the highest luminosity record at KEKB, 8 x 10$^{35}$ cm$^{-2}$s$^{-1}$ is necessary.

    Linear e+e- colliders uniquely offer the opportunity to study collisions with longitudinally polarized electron and positron beams. In recent studies of precision tests of the Standard Model at the International Linear Collider, it has been seen that this capability can play an unexpectedly important role.
