15 صفحه اولQcd Constraints on Form Factor Shapes * †
This talk presents an introduction to the use of dispersion relations to constrain the shapes of hadronic form factors consistent with QCD. The applications described include methods for studying |Vcb| and |Vub|, the strange quark mass, and the pion charge radius.
متن کاملTuring universality of the Biochemical Ground Form
We explore the expressive power of languages that naturally model biochemical interactions with relative to languages that naturally model only basic chemical reactions, identifying molecular association as the basic mechanism that distinguishes the former from the latter. We use a process algebra, the Biochemical Ground Form (BGF), which extends with primitives for molecular association CGF, a...
متن کاملMatrix universality of gauge and gravitational dynamics
A simple cubic matrix model is presented, which has truncations that, it is argued, lead at the classical level to a variety of theories of gauge fields and gravity. The latter includes Chern-Simons theory in d = 3, and BF theory and general relativity in d = 4. General relativity coupled to Yang-mills theory for any SU(N) may also arise from quantum corrections. On the basis of these results w...
متن کاملLarge Nc universality of the baryon Isgur-Wise form factor: The group theoretical approach.
In a previous article, it has been proved under the framework of chiral soliton model that the same Isgur–Wise form factor describes the semileptonic Λb → Λc and Σ (∗) b → Σ (∗) c decays in the large Nc limit. It is shown here that this result is in fact independent of the chiral soliton model and is solely the consequence of the spin-flavor SU(4) symmetry which arises in the baryon sector in t...
