  Effective field theory methods provide us with a useful tool for separating short and long distance fluctuations. Examples include the Electroweak Hamiltonian (separating mb,c ≪ mW ), Heavy Quark Effective Theory (separating ΛQCD ≪ mb), and Chiral Perturbation Theory (separating

• Inclusive Decays of Bottom Hadrons in New Formulation of Heavy Quark Effective Field Theory

  سند علمی۱۹۹۹Y. A Yan, Y. L Wu

  We apply the new formulation of heavy quark effective field theory (HQEFT) to the inclusive decays of bottom hadrons. The long-term ambiguity of using heavy quark mass or heavy hadron mass for inclusive decays is clarified within the framework of the new formulation of HQEFT. The

• Effective Field Theory of Heavy Mesons

  سند علمی۱۹۹۸Hai-Yang Cheng

  In this paper we present a detailed formulation for a recently proposed effective field theory to describe the nonperturbative QCD dynamics of heavy mesons. This effective theory incorporates with heavy quark symmetry (HQS) and the heavy quark effective theory (HQET). Heavy meson

• Effective Field Theory and Heavy Quark Physics ( 2004

  سند علمی۲۰۰۸Matthias Neubert

  These notes are based on five lectures presented at the 2004 Theoretical Advanced Study Institute (TASI) on “Physics in D ≥ 4”. After a brief motivation of flavor physics, they provide a pedagogical introduction to effective field theory, the effective weak Lagrangian, and the te

• Decay Properties of QQ̄ Mesons in Potential Models and Effective Field Theories

  سند علمی۲۰۰۸Ajay Kumar Rai, Bhavin Patel

  The decay rates of QQ̄ mesons (Q ε c,b) are studied in the NRQCD formalism in terms of their short distance and long distance coefficients. The long distance coefficients are obtained through phenomenological potential model description of the mesons. The mass spectrum of the cc̄
