“…We are exploring two options for running the PROTOPLASMA experiment: Fermilab Main Ring or the Tevatron beamline. The ORKA [6] will make a precise measurement of the branching ratio of (K + → π + νν) decay. If the decay occurs at the standard model rate, 200 events are expected per year of operation.…”

Abstract. Generation of TeV-scale electron beams using conventional RF technology appears expensive for building the next generation of colliders. Proton-driven plasma-wakefield acceleration of electrons promises an alternative route to generate TeV-scale electron beams using existing proton machines. PROTOPLASMA is the proposed R&D project at Fermilab that plans to use a proton beam driven plasma-wakefield to accelerate electrons. The project is planned in stages with the project's path guided by simulations. First, a 60-120 GeV proton beam will be injected into 1-2 meters of plasma to observe selfmodulation instability in the proton beam. Next, an injected 5 MeV electron beam will be accelerated by the plasma. In this paper, we report on the basic project plan and outline our staged approach. We report on first simulation results that show self-modulation of a proton bunch and discuss beam optics requirements and other limits.

“…There's one each of charged and neutral searches in the last generation, BNL E787/949 [3] and KEK E391a [4], one each underway at the moment, CERN NA62 [5] and J-PARC's KOTO [6] and one each contemplated for the future, ORKA [7] at Fermilab and a yet-to-be-named KOPIO-like experiment at Project-X [8]. Each mode features two experimental techniques that have been used or proposed.…”

“…However, the spontaneous global symmetry breaking produces a Nambu-Goldstone boson known as axion that must be invisible because, if the axion would be coupled to the SM fermions, it should had been produced in the colliders. Additionally, the coupling of the axion to FCNC is highly suppressed by the processes such as K → πa [49][50][51][52][53] and μ → ea [54]. One way to make the axion invisible is to assume that there is an additional exotic quark with non-vanishing PQ charge so that the axion is disconnected from the low energies physics [55].…”

We propose a non-universal U(1) X gauge extension to the standard model (SM) and an additional Peccei–Quinn (PQ) global symmetry to study the mass hierarchy and strong CP problem. The scheme allows us to distinguish among fermion families and to generate the fermionic mass spectrum of particles of the SM. The symmetry breaking is performed by two scalar Higgs doublets and two scalar Higgs singlets, where one of these has the axion which turns out to be a candidate for cold dark matter. The exotic sector is composed by one up-like T and two down-like J 1,2 heavy quarks, two heavy charged leptons , one additional right-handed neutrino per family , and an invisible axion a. In addition, the large energy scale associated to the breaking of the PQ-symmetry gives masses to the right-handed neutrinos in such a way that the active neutrinos acquire eV-mass values due to the see-saw mechanism. On the other hand, from the non-linear effective Lagrangian, the flavour changing of the down quarks and charged leptons with the axion are considered.
