Non-zero Fermion Modes Contribution to the Instanton-Induced Electroweak Processes at High Energies

چکیده
where √ s is c.m. energy of the process, Esp ≈ 4 √ 6πmw g ≈ 16 TeV energy of sphaleron [7]. The first term in ”Holy Grail” function F (ε) is ’t Hooft suppression factor [1], the second corresponds to the multiple W and Higgs bosons production in Gauss approximation [4, 5], the third is a contribution of tree boson graphs [8, 9]. Boson loops [10] and fermion contribution [11] are accumulated in preexponent factor. One can naively suppose that F (ε) → 0 if √s → Esp and cross-section (1) can reach observable value . In this case pre-exponent constant in (1) can be important. Exact behavior of ”Holy Grail” is unknown at ε ≥ 1 and a question about possibility of observation of anomalous baryon number violation is still opened.

New Electroweak Instanton and Possible Breakdown of Unitarity
Potential implications of a new constrained instanton solution in the electroweak standard model are discussed. Notably, there may be a non-perturbative unitarity violating contribution to the total cross-section at high collision energies.
متن کاملFermion zero-modes of a new constrained instanton in Yang-Mills-Higgs theory
Self-consistent Ansätze are presented for the leftand right-handed isodoublet fermion zeromodes of the constrained instanton I⋆ in the vacuum sector of euclidean SU(2) Yang-Mills-Higgs theory. These leftand right-handed fermion wave functions do not coincide and, most likely, have a relative shift between their peaks. This may be important for the fermion zero-mode contribution to the euclidean...
متن کاملNon-zero Quark Modes Contribution to the QCD-Instanton-Induced Deep Inelastic Scattering
Instanton-induced deep-inelastic processes are considered. Unlike previous results we calculate nonzero quark modes contribution. As was shown [1], QCD-instantons can appear at the intermediate stage of deep inelastic scattering (DIS) and be, in principle, observed at HERA (DESY) [2, 3]. Specifically, instantons can be produced in quark-gluon subprocess (Fig.1).
متن کاملAvalanche in the Valley (Fermions, Anomaly and Unitarity in High-Energy Electroweak Interactions)
Problems related to fermions, unitarity and chiral anomaly in high energy electroweak interactions, are investigated. Particular attention is paid to the correct functional integration over fermion fields in the background of instanton-antiinstanton type configurations. This leads to an expansion of correlation functions in terms of a small parameter, ρ/R, when the instanton-antiinstanton separ...
متن کاملInstantons and the Chiral Phase Transition at non-zero Baryon Density
We study an interacting ensemble of instantons at finite baryon chemical potential. We emphasize the importance of fermionic zero modes and calculate the fermion induced interaction between instantons at non-zero chemical potential. We show that unquenched simulations of the instanton ensemble are feasible in two regimes, for sufficiently small and for very large chemical potential. At very lar...
