A solution to the classical field equations in the massless (1+1)-dimensional O(3) sigma model is found, which describes a multi-particle instanton-like transition at high energy. In the limit of small number of initial particles, the number of final particles is shown to be also small, and the probability of the transition is suppressed by exp(−2S 0), where S 0 is the instanton action. This so...
متن کاملInstanton–Like Transitions at High Energies in (1+1) Dimensional Scalar Models
Instanton-like transitions (“shadow processes”) are considered in (1+1) dimensional models with one scalar field whose potential is a quadratic well with a cliff. The corresponding classical boundary value problem is solved, and the semiclassical transition probabilities are found in a rather wide range of energies and the numbers of initial particles.
متن کاملFermion Modes in Instanton-Anti-Instanton Background in (1+0)-dimensional Model
We evaluate the eigenvalues of Dirac operator in the background of instanton-antiinstanton configuration (I-̄I), in a simple (1+0)-dimensional model, and find that quasizero-mode disappears for the closely localized I-̄I configurations. This result suggests that the configurations which are dominant at high energy in the valley method are actually non-anomalous ones and irrelevant to fermion numb...
متن کاملInstanton Equations for the Supersymmetric CP N − 1 Sigma Model on Non ( anti ) commutative Superspace
Studies of strings with non-trivial classical values of its field components have brought about new development in quantum field theories. If one allows some of the field components to posses background values on D-branes, one obtains new classes of quantum field theories in the low energy limits of string theory. They have novel features due to the non(anti)commutativity (NC) properties of spa...
متن کاملFast Blow Up in the (4+1)-dimensional Yang Mills Model and the (2+1)-dimensional S Sigma Model
We study singularity formation in spherically symmetric solitons of the (4+1) dimensional Yang Mills model and the charge two sector of the (2+1) dimensional S2 sigma model, also known as CP 1 wave maps, in the adiabatic limit. These two models are very similar. Studies are performed numerically on radially symmetric solutions using an iterative finite differencing scheme. Predictions for the e...
