θ–instantons in SU(2) Higgs theory
We consider topology changing processes in SU(2)–Higgs theory. In the Standard Model of particle physics they are accompanied by baryon– and lepton–number non–conservation. At fixed energy and multiplicity of initial state, these processes are described by classical θ–instanton solutions. We describe these solutions and calculate the suppression exponents for the probabilities of the topology c...
متن کاملOn Invariant Theory of Θ-groups
The ground field k is algebraically closed and of characteristic zero. Throughout, G is a connected and simply connected semisimple algebraic group, g is its Lie algebra, and Φ is the Cartan–Killing form on g; l = rk g. Int g (resp. Aut g) is the group of inner (resp. all) automorphisms of g; N is the nilpotent cone in g. For x ∈ g, z(x) is the centraliser of x in g. Let g = ⊕i∈Zmgi be a period...
متن کاملκ-deformed gauge theory and θ-deformed gravity
Noncommutative (deformed, quantum) spaces are deformations of the usual commutative space-time. They depend on parameters, such that for certain values of parameters they become the usual space-time. The symmetry acting on them is given in terms of a deformed quantum group symmetry. In this work we discuss two special examples, the θ-deformed space and the κ-deformed space. In the case of the θ...
متن کاملKAM theory in configuration space
A new approach to the Kolmogorov-Arnold-Moser theory concermng the existence of invariant ton having prescnbed frequencies îs presented It îs based on the Lagrangian formahsm m configuration space instead of the Hamiltonian formahsm in phase space used in earher approaches In particular, the construction of the invariant ton avoids the composition of infinitely many coordinate transformations T...
متن کاملAlgebraic K - Theory and Configuration Spaces
Its importance lies in the fact that the right hand side of the above equivalence (which wewill briefly refer to as a configuration space model) is a much smaller space than the function space on the left, and thus is much easier to deal with. The second author noted that in the configuration space model, one can replace the X" by spaces like BGln(R). For there is an obvious ~n action on BGln(R...
