Superconducting magnets and technologies for future colliders
The implications of accelerator magnet R&D towards future colliders are reviewed and discussed. It starts with a brief overview of the present and future accelerator facilities which rely on the significant advances and innovations in key technologies. Then advances and needs for present key projects and studies are expanded on specific examples. This provides the lead to discuss the recent progress in accelerator magnet R&D and the future plans. We conclude with a summary of our view of the major development drivers and future perspectives. -
RF Technologies for Future Colliders
Particle colliders remain indispensable scientific instruments to discover and study new elementary particles and fundamental forces of nature. Whether the collider is a factory (used to improve precision of measuring properties of already discovered particles or to enable studies of rare decay channels), an energy frontier machine (aimed at discovering new particles and forces), a heavy ion collider (allowing studies of what the universe looked like in the early moments after its creation), or an electron-hadron collider (where electrons are used for probing heavy ions or protons to study the fundamental force binding all visible matter), the radio frequency technologiesmore » -
Jets and Jet Substructure at Future Colliders
Even though jet substructure was not an original design consideration for the Large Hadron Collider (LHC) experiments, it has emerged as an essential tool for the current physics program. We examine the role of jet substructure on the motivation for and design of future energy Frontier colliders. In particular, we discuss the need for a vibrant theory and experimental research and development program to extend jet substructure physics into the new regimes probed by future colliders. Jet substructure has organically evolved with a close connection between theorists and experimentalists and has catalyzed exciting innovations in both communities. We expect suchmore » -
Electron-Hadron Colliders: EIC, LHeC and FCC-eh
Electron-hadron colliders are the ultimate tool for high-precision quantum chromodynamics studies and provide the ultimate microscope for probing the internal structure of hadrons. The electron is an ideal probe of the proton structure because it provides the unmatched precision of the electromagnetic interaction, as the virtual photon or vector bosons probe the proton structure in a clean environment, the kinematics of which is uniquely determined by the electron beam and the scattered lepton, or the hadronic final state accounting appropriately for radiation. The Hadron Electron Ring Accelerator HERA (DESY, Hamburg, Germany) was the only electron-hadron collider ever operated (1991–2007) andmore » -
Production of $π^0$ and $$\eta$$ mesons in $$\mathrm{U+U}$$ collisions at $$\sqrt {s_{NN}} = 192$$ $$\mathrm {GeV}$$
The PHENIX experiment at the Relativistic Heavy Ion Collider measured $π^0$ and $$\eta$$ mesons at midrapidity in $$\mathrm{U+U}$$ collisions at $$\sqrt {s_{NN}} = 192$$ $$\mathrm {GeV}$$ in a wide transverse momentum range. Measurements were performed in the $π^0(η) → γγ$ decay modes. A strong suppression of $π^0$ and $$\eta$$ meson production at high transverse momentum was observed in central $$\mathrm{U+U}$$ collisions relative to binary scaled p + p results. Yields of $π^0$ and $$\eta$$ mesons measured in $$\mathrm{U+U}$$ collisions show similar suppression pattern to those measured in Au + Au collisions at $$\sqrt {s_{NN}} = 200$$ $$\mathrm {GeV}$$ for similarmore » -
The Future Prospects of Muon Colliders and Neutrino Factories
The potential of muon beams for high energy physics applications is described along with the challenges of producing high quality muon beams. Two proposed approaches for delivering high intensity muon beams, a proton driver source and a positron driver source, are described and compared. The proton driver concepts are based on the studies from the Muon Accelerator Program (MAP). Here, the MAP effort focused on a path to deliver muon-based facilities, ranging from neutrino factories to muon colliders, that could span research needs at both the intensity and energy frontiers. The Low EMittance Muon Accelerator (LEMMA) concept, which uses amore »
