“…Whereas the 4.5-and 5-GeV cuts employ muon range in the target, the "9-GeV" cut requires the spectrometer reconstruction of the nonleading muon. to Czyz et al 2 and Brown et al 1 These agreed within 3%, and were also in agreement with the approximate calculation (using a virtual-photon approximation) in Refs. 1 and 9.…”

We present a measurement of neutrino tridents, muon pairs induced by neutrino scattering in the Coulomb field of a target nucleus, in the Columbia-Chicago-Fermilab-Rochester neutrino experiment at the Fermilab Tevatron. The observed number of tridents after geometric and kinematic corrections, 37.0 ± 12.4, supports the standard-model prediction of 45.3 ± 2.3 events. This is the first demonstration of the W-Z destructive interference from neutrino tridents, and rules out, at 99% C.L., the V -A prediction without the interference.PACS numbers: 13.10.+q, 12.15.Ji, 14.80.Er, 25.30.Pt A neutrino trident is the scattering of a neutrino in the Coulomb field of a target nucleus (TV),

“…Even if the weak bosons were not produced directly due to, e.g., their large masses, their existence could make the trident production rate different from that of the pure V-A theory (e.g., Refs. [63][64][65][75][76][77][78][79][80])…”

The physics of neutrino-nucleus cross sections is a critical probe of the Standard Model and beyond. A precise understanding is also needed to accurately deduce astrophysical neutrino spectra. At energies above ∼ 5 GeV, the cross section is dominated by deep inelastic scattering, mediated by weak bosons. In addition, there are subdominant processes where the hadronic coupling is through virtual photons, γ * : (on-shell) W -boson production (e.g., where the underlying interaction is ν +γ * → − +W + ) and trident production (e.g., where it is ν +γ * → ν + − 1 + + 2 ). These processes become increasingly relevant at TeV-PeV energies. We undertake the first systematic approach to these processes (and those with hadronic couplings through virtual W and Z bosons), treating them together, avoiding common approximations, considering all neutrino flavors and final states, and covering the energy range 10 -10 8 GeV. In particular, we present the first complete calculation of W -boson production and the first calculation of trident production at TeV-PeV energies. When we use the same assumptions as in prior work, we recover all of their major results. In a companion paper [1], we show that these processes should be taken into account for IceCube-Gen2.

“…The calculated cross section for the coherent process v + Z -~ vjiiiZ is several orders of magnitude smaller than the dimuon signal, and the corresponding incoherent process has an even smaller cross section. 7 Without the intervention of higher-order-weak or weak-electromagnetic interactions which are expected at a much lower rate, the only known mechanism that can produce trilepton final states accompanied by hadrons is the production and weak decay of one or more new particles. Such particles could be hadrons which carry a new quantum number 8 not conserved by the interaction responsible for the decay.…”
