<!--HTML-->The Muon Collider, one of the options considered for the future of particle physics at the energy frontier, poses many challenges to accelerator technology. The magnets for the muon beam production, acceleration and collision are one of the most demanding systems, for many reasons. Firstly, collider performance in terms of energy and luminosity translates in the demand for high fields, high field rates, and large apertures, thus challenging magnet science and engineering well beyond state-of-the-art. At the same time, the operating environment is very harsh: the decay of highly energetic muons, whose products are difficult to shield, results in large heat and radiation loads to be managed efficiently. Finally, a Muon Collider, as any other future collider at the energy frontier, needs to be affordable and produce sustainable science. The magnets, the single system with the largest cost and power figures, are naturally at the center of the attention also from this point of view. We base this note on analytical and scaling relations to indicate what and how the magnet challenges of the Muon Collider can be mastered, and what needs to be done. Most interesting, addressing magnet technology challenges for a Muon Collider will benefit any future collider at the energy frontier, as well as many other fields of scientific and societal application of magnet technology.

We elaborate on the production of the Standard Model Higgs particle at highenergy e + e − colliders through the reaction e + e − → ZH. Particular emphasis is put on the intermediate mass range. In addition to the signal we discuss in detail the background processes. Angular distributions which are sensitive to the spin and parity of the Higgs particle are analyzed. 1 1. The Physical Basis The fundamental particles in the Standard Model (SM), gauge bosons, leptons and quarks, acquire their masses by means of the Higgs mechanism [1]. The masses are generated through the interaction with a non-zero scalar field in the ground state, inducing the spontaneous breaking of the electroweak SU(2)I×U(1)Y symmetry down to the electromagnetic U(1)EM symmetry. To accommodate the well established electromagnetic and weak phenomena, this mechanism requires the existence of at least one weak iso-doublet scalar field. The three Goldstone bosons among the four degrees of freedom are absorbed to build up the longitudinal polarization states of the massive W ± , Z bosons. One degree of freedom is left-over, corresponding to a real physical particle. The discovery of this Higgs particle

This codebase generates all the simulations and data presented in our paper [1]. Briefly, two cells are modeled energetically within the phase-field framework and undergo head-on collisions. Our main goal is to study how the speed and contact angle of the cell affect its chances to remain persistent upon head-on collisions. [1] Zadeh, Pedrom, and Brian A., Camley.

We report measurements of the pro le of the wake eld-induced energy loss of the beam along the 1.2 km long SLC North Collider Arc. By measuring orbit di erences in dispersive regions for di erent bunch lengths, the wake eld-generated energy loss is distinguished from losses due to synchrotron radiation. Calculations of the wake elds arising in the arc chambers are given and used in simulations of the evolution of the longitudinal phase space along the arcs. The measurements are consistent with the calculations. By this method wake eld anomalies in the arcs can be found. In addition, with a non-standard setting of parameters the bunch can be compressed down to 50 m, and the wake eld e ect of an ultra-short bunch can be observed. Results for the nal focus wake eld-induced losses are also given.

. Parameters are given of machines with center-of-mass (CoM) energies of 3 TeV and 400 GeV but, besides a comment on neutrino radiation, the paper concentrates on progress on the design of a machine to operate at a light Higgs mass, assumed, for this study, to be 100 GeV (CoM). INTRODUCTION The possibility of muon colliders was introduced by Skrinsky et al. [1] and Neuffer [2]. More recently, a collaboration of over 100 members, lead by BNL, FNAL, LBNL, BNIP, University of Mississippi, Princeton University and UCLA has been formed to coordinate studies on specific designs. Work has been done on designs at a 3-4 TeV, 0.4-0.5 TeV and ß100 GeV [3--7]. Tb. 1 gives the parameters of such colliders, and Figs. 1 and 2 show possible outlines of the 3 TeV and 100 GeV machines. The original motive for considering muon colliders was the effective energy advantage of any lepton collider over hadron machines, together with the fact that muons, unlike electrons, generate negligible synchrotron radi...

Lattice And Accelerator--Detector, N. M. Gelf, N. V. Mokhov · 2007
The design for a high-luminosity + - superconducting storage ring is presented based on first-pass calculations. Special attention is paid to two low-# interaction regions (IR) whose optics are literally interlaced with the collider detectors. Various sources of backgrounds in IR are explored via realistic Monte Carlo simulations. An improved design of the collider lattice in the neighborhood of the interaction points (IP) is determined by the need to reduce significantly background levels in the detectors. I. INTRODUCTION An increasing interest to a high-energy high-luminosity + - collider project [1], [2] is based on the high physics potential of such a machine [3] beyond what can be accomplished at e + e - and pp (LHC) colliders. Even though there are some problems to be examined, especially on a technical side, no obvious show stopper has yet been found [4]. The collider complex will consist of a few essential parts: a high-intensity rapid-cycling 10 to 30 GeV proton synchrotr...

The potential of hadron colliders to explore the physics of CP violation in B decays is discussed. B physics experiments which have hopes of achieving enough sensitivity to observe and study CP violation and the related topic of B s mixing are being constructed at several locations: at new asymmetric energy e + e \\Gamma colliders at SLAC 1) and KEK 2) ; at the existing symmetric energy e + e \\Gamma collider 3) , CESR, at Cornell; at a novel fixed target experiment using the proton beam halo at HERA, the HERA-B experiment 4) ; and in ¯ p \\Gamma p experiments using upgraded versions of the two `general purpose&apos; detectors, CDF 5) and D0 6) , at the Fermilab Tevatron. This may truly be characterized as a `world-wide&apos; effort. All of the experiments mentioned above are quite limited in their statistical precision and some are also quite narrow in scope. While these experiments are likely to begin the study of CP violation, there are many reasons to believe that they will...

A linear collider is the next large project of particle physics following the commissioning of the LHC.By 2012 feedback can be expected from the LHC on the spectrum of new physics below 1 TeV.This information will be timely for a revision of the European Strategy for particle physics and the possible decision for a linear collider for which the ILC is the only contender that could promptly be realized.Similar strategic considerations are made in Japan so that currently two regions are exploring the implications of hosting the ILC.A multi-TeV collider would require considerable R&D, which is well under way for the CLIC project.The status of these two projects is described.
