2. Resonance matrix elements on the lattice.

Author

Agadjanov, Andria, Bernard, Véronique, Meißner, Ulf-G., and Rusetsky, Akaki

Subjects
LATTICE theory, PION production, PIONS, PHOTOELECTRONS, PHYSICS research
Abstract

The notion of resonance matrix elements is discussed. The analogue of the Lellouch-Lüscher formula for the pion photo(electro)production amplitude in the Δ(1232) resonance region is given. A prescription for the pole extraction of the ΔNγ* transition form factors is provided. Theoretical prospects on the lattice calculation of B → K*(892)l+l- form factors are briefly summarized.

3. Radiative decays of resonances on the lattice.

Author

Agadjanov, Andria, Bernard, Véronique, Meißner, Ulf-G., and Rusetsky, Akaki

Subjects
RESONANCE, LATTICE dynamics, MATRICES (Mathematics), PHASE transitions, FORM factor (Nuclear physics)
Abstract

We discuss a generalization of the Lüscher approach to the calculation of the matrix elements of the unstable states. A theoretical framework for the lattice extraction of the ΔNγ* transition form factors is formulated. The procedure to measure the form factors at the resonance pole is given. The current theoretical progress on the B→K*γ* decays is briefly summarized. [ABSTRACT FROM AUTHOR]

Abstract

We discuss a generalization of the Lüscher approach to the calculation of the matrix elements of the unstable states. A theoretical framework for the lattice extraction of the ΔNγ ∗ transition form factors is formulated. The procedure to measure the form factors at the resonance pole is given. The current theoretical progress on the B→K∗γ ∗ decays is briefly summarized. [ABSTRACT FROM AUTHOR]
