متن کاملWeak transition matrix elements from finite-volume correlation functions
The two-body decay rate of a weakly decaying particle (such as the kaon) is shown to be proportional to the square of a well-defined transition matrix element in finite volume. Contrary to the physical amplitude, the latter can be extracted from finite-volume correlation functions in euclidean space without analytic continuation. The K → ππ transitions and other non-leptonic decays thus become ...
متن کاملFinite - Element Lattice Hamiltonian Matrix Elements
The finite-element approach to lattice field theory is both highly accurate (relative errors ∼ 1/N2, where N is the number of lattice points) and exactly unitary (in the sense that canonical commutation relations are exactly preserved at the lattice sites). In this paper we construct matrix elements for the time evolution operator for the anharmonic oscillator, for which the continuum Hamiltoni...

متن کاملNonperturbative production of multiboson states and quantum bubbles.
The amplitude of production of n on-mass-shell scalar bosons by a highly virtual field φ is considered in a λφ theory with weak coupling λ and spontaneously broken symmetry. The amplitude of this process is known to have an n! growth when the produced bosons are exactly at rest. Here it is shown that for n ≫ 1/λ the process goes through ‘quantum bubbles’, i.e. quantized droplets of a different ...
