SCET sum rules for Λ b → Λℓ + ℓ − , Λγ decays

Journal of High Energy Physics
We construct light-cone sum rules for various types of effective form factors in the Λ b → Λℓ + ℓ − and Λ b → Λγ decays by analyzing vacuum-to-Λ b (or γ *-to-Λ b ) correlation functions with the light Λ-baryon interpolating current.

Highlight of Charm Physics at BESIII

EPJ Web of Conferences, 2014
In this talk, we present the recent results of charm physics from the BESIII collaboration. This talk covers the studies of the leptonic and semi-leptonic decays of D mesons, and the measurement of the strong phase difference based on the quantum ...

Constraining |V cs | and physics beyond the Standard Model from exclusive (semi)leptonic charm decays

Journal of High Energy Physics
We study the available data on exclusive leptonic and semileptonic c → sℓ + ν decays within the Standard Model and beyond. Our analysis accounts for theory correlations between the relevant hadronic matrix elements through application of dispersive ...

Form factors for semi-leptonic B decays

, 2016
Semi-leptonic $B$ decays provide promising channels to test the Standard Model, search for signs of new physics, or determine fundamental parameters like CKM matrix elements.

Total decay rates of B mesons at NNLO-QCD

Journal of High Energy Physics
We update the Standard Model (SM) predictions for the lifetimes of the B +, B d and B s mesons within the heavy quark expansion (HQE), including the recently determined NNLO-QCD corrections to non-leptonic decays of the free b-quark.

Review of D Semi-leptonic Decays

, 2012
Semi-leptonic D decays continue to play an important role in the field of flavor physics. During this presentation, recent measurements from pseudo-scalar to pseudo-scalar modes, pseudo-scalar to vector modes, and rare modes will be discussed. These results are important for many purposes, such as validating the machinery of lattice QCD, extracting CKM

Challenging B ¯ s → D s ∗ $$ {\overline{B}}_{(s)}\to {D}_{(s)}^{\left(\ast \right)} $$ form factors with the heavy quark expansion

Journal of High Energy Physics
Recent publications by three lattice QCD collaborations have provided an unprecedented wealth of theoretical predictions for the B ¯ q → D q ∗ $$ {\overline{B}}_q\to {D}_q^{\left(\ast \right)} $$ form factors, for spectator flavours q = u/d and q = s. We
