We report the "state of the art" of the problem of $B+L$ violation in high-energy electroweak scatterings. Results of various analyses point toward (though do not prove rigorously yet) the "half-suppression", i.e., that the $B+L$ violating cross section remains suppressed at least by the negative exponent of the single instanton action, at all energies. Most interesting techniques developed in this field are reviewed. Particular attention is paid to unitarity constraints on the anomalous… 
B+L violation at colliders and new physics
A bstractChiral electroweak anomalies predict baryon (B) and lepton (L) violating fermion interactions, which can be dressed with large numbers of Higgs and gauge bosons. The estimation of the total
Impact of new physics on B + L violation at colliders
In the Standard Model, chiral electroweak anomalies predict nonperturbative interactions that violate baryon ($B$) plus lepton number ($L$). The potential observability of these processes at
Electroweak baryon number non-conservation in the early Universe and in high-energy collisions
We review recent progress in the study of the anomalous baryon number non-conservation at high temperatures and in high energy collisions. Recent results on high temperature phase transitions are
An upper bound on the total cross-section for electroweak baryon number violation
An upper bound on the total cross-section of s-wave electroweak instanton/sphaleron induced baryon plus lepton number violating processes is presented. It is obtained by exploiting a recently
Electroweak instantons/sphalerons at VLHC?
There is a close analogy between electroweak instanton-induced baryon plus lepton number (B + L) violating processes in Quantum Flavor Dynamics (QFD) and hard QCD instanton-induced chirality
Band structure in Yang-Mills theories
A bstractWe show how Yang-Mills theory on S3 × ℝ can exhibit a spectrum with continuous bands if coupled either to a topological 3-form gauge field, or to a dynamical axion with heavy Peccei-Quinn
Instantons in deep-inelastic scattering: The simplest process
Instanton calculations in QCD are generically plagued by infrared divergencies associated with the integration over the instanton size ϱ. Here, we demonstrate explicitly that the typical inverse hard
Electroweak instantons as a solution to the ultrahigh-energy cosmic ray puzzle
Abstract We propose a scenario in which a simple power-like primary spectrum for protons with sources at cosmological distances leads to a quantitative description of all the details of the observed
Tunneling in a uniform one-dimensional superfluid: Emergence of a complex instanton
In a uniform ring-shaped one-dimensional superfluid, quantum fluctuations that unwind the order parameter need to transfer momentum to quasiparticles (phonons). We present a detailed calculation of

Multi-W(Z) Production in High-Energy Collisions?
There exists the possibility that the cross-section for the nonperturbative production of many, ${\cal O}(\alpha_W^{-1} \simeq 30 )$, weak gauge bosons may be as large as ${\cal O}(100\ {\rm pb}\ -\

Abstract A solution to the classical field equations in the massless (1 + 1)-dimensional O(3) sigma model is found, which describes a multiparticle instanton-like transition at high energy. In the
