“…• The 120 GeV ring receives the 8.94 GeV protons to be accelerated to 120 GeV energy, which are sent to the antiproton source to produce the antiprotons. Lepton colliders might also share the tunnel [39,40,[67][68][69][70][71][72][73][74][75][76][77][78].…”

“…There it can be seen the gluon fusion (gg) process dominates the lighter Higgs production in pp collisions up to the 1 TeV range. The qq part of the total cross section will be more important at higher masses, scaling with mass of the object M over center of mass collision energy M/ √ s. The cross section to produce high mass objects in pp collisions can be of order 10 times higher than it is for proton-proton collisions[39,40].…”

Currently new physics is being explored with the Large Hadron Collider at CERN and with Intensity Frontier programs at Fermilab and KEK. The energy scale for new physics is known to be in the multi-TeV range, signaling the need for a future collider which well surpasses this energy scale. A 10 34 cm −2 s −1 luminosity 100 TeV proton-antiproton collider is explored with 7× the energy of the LHC. The dipoles are 4.5 T to reduce cost. A protonantiproton collider is selected as a future machine for several reasons. The cross section for many high mass states is 10 times higher in pp than pp collisions. Antiquarks for production can come directly from an antiproton rather than indirectly from gluon splitting. The higher cross sections reduce the synchrotron radiation in superconducting magnets and the number of events per bunch crossing, because lower beam currents can produce the same rare event rates. Events are also more centrally produced, allowing a more compact detector with less space between quadrupole triplets and a smaller β * for higher luminosity. To adjust to antiproton beam losses (burn rate), a Fermilab-like antiproton source would be adapted to disperse the beam into 12 different momentum channels, using electrostatic septa, to increase antiproton momentum capture 12 times. At Fermilab, antiprotons were stochastically cooled in one Debuncher and one Accumulator ring. Because the stochastic cooling time scales as the number of particles, two options of 12 independent cooling systems are presented. One electron cooling ring might follow the stochastic cooling rings for antiproton stacking. Finally antiprotons in the collider ring would be recycled during runs without leaving the collider ring, by joining them to new bunches with snap bunch coalescence and synchrotron damping. These basic ideas are explored in this work on a future 100 TeV proton-antiproton collider and the main parameters are presented.

“…In order to complete the picture, we should mention other collider projects that were considering an application of the CW scheme such as SuperB [11] and SuperTau-Charm [12] factories in Italy, a 500 GeV e+e-collider in a 233-km tunnel [13] in USA, and an upgrade option of the LHC based on collisions of very flat bunches [14,15].…”

Abstract.A new concept of nonlinear focusing of colliding bunches, called Crab Waist (CW) collision scheme, has been proposed at LNF INFN. It has been successfully tested at the Italian lepton collider DANE in operational conditions providing luminosity for two different experimental detectors, SIDDHARTA and KLOE-2. Considering a high efficiency of the scheme for increasing collision luminosity and its relative simplicity for implementation several new collider projects have been proposed and are under development at present. These are the SuperKEKB B-factory ready to start commissioning in 2016 in Japan, the SuperC-Tau factory proposed in Novosibirsk and entered in the short list of Russian mega-science projects, the new 100-km electron-positron Future Circular Collider (FCC-ee) under design study at CERN and some others. In this paper we describe the CW collision scheme, discuss its advantages and report principal results achieved at the electron-positron -factory DANE.

“…The observed low mass Higgs boson can be reached also with storage ring e + e − colliders (SRC). Several proposals [3,4,5,6,7,8,9] for a 2E 0 = 240 GeV SRC for the study of the Higgs boson in e + e − → HZ have recently been put forward. Lower cost and reliance on firmly established technologies and higher luminosity are cited as these projects' advantages over an LC.…”
