Тема семинара: «Weak decays of doubly heavy baryons»

Докладчик: Жомарт Тюлемисов

Аннотация:

The main objective of the talk is discussion of research semileptonic and a broad class of nonleptonic decays of the doubly charmed baryons. The decays include as the factorizable diagrams as the nonfactorizable quark diagrams. Latter appear in studying of nonleptonic two-body decays of the doubly heavy baryons. Nonfactorizable contributions describing by three loop diagrams which can be calculated by general principles of covariant quark model. Also, we demonstrate calculation of partial nonleptonic decays width of Lambda-hyperon taking into account as quark diagrams with various topology as pole diagrams with intermediate baryon resonances.
