On the gauge-invariance of SCET beyond leading power

Philipp Böer, Patrick Hager

We point out that the gauge-invariance of the subleading Lagrangian of soft-collinear effective theory is realised in an intricate way through momentum-conservation violating contr…

Muon-electron backward scattering: a prime example for endpoint singularities in SCET

Guido Bell, Philipp Böer, Thorsten Feldmann

We argue that energetic muon-electron scattering in the backward direction can be viewed as a template case to study the resummation of large logarithms related to endpoint diverge…

Light-cone distribution amplitudes of light mesons with QED effects

Martin Beneke, Philipp Böer, Jan-Niklas Toelstede +1

We discuss the generalization of the leading-twist light-cone distribution amplitude for light mesons including QED effects. This generalization was introduced to describe virtual…

QED factorization of two-body non-leptonic and semi-leptonic $B$ to charm decays

Martin Beneke, Philipp Böer, Gael Finauri +1

The QCD $\times$ QED factorization is studied for two-body non-leptonic and semi-leptonic $B$ decays with heavy-light final states. These non-leptonic decays, like $\bar{B}^0_{(s)}\t…

Angular Analysis of \boldmath $Λ_{b} \to Λ_{c} (\to Λ π) ℓ ν ˉ$

Philipp Böer, Ahmet Kokulu, Jan-Niklas Toelstede +1

We revisit the decay $Λ_{b}^{0} \to Λ_{c}^{+} ℓ^{-} ν ˉ$ ( $ℓ = e, μ, τ$ ) with a subsequent two-body decay $Λ_{c}^{+} \to Λ^{0} π^{+}$ in the Standard Model and in generic New Physics models. The…

Testing lepton flavour universality in semileptonic $Λ_{b} \to Λ_{c}^{*}$ decays

Philipp Böer, Marzia Bordone, Elena Graverini +3

Lepton Flavour Universality tests with semileptonic $Λ_{b} \to Λ_{c}^{*}$ decays are important to corroborate the present anomalies in the similar ratios $R_{D^{(*)}}$ , and can provide com…

QCD Factorization for $B \to π π ℓ ν$ Decays at Large Dipion Masses

Philipp Böer, Thorsten Feldmann, Danny van Dyk

We introduce a factorization formula for semi-leptonic $b \to u$ transitions in the exclusive decay mode $B^{-} \to π^{+} π^{-} ℓ^{-} ν ˉ_{ℓ}$ in the limit of large pion energies and la…

Angular Analysis of the Decay $Λ_{b} \to Λ (\to N π) ℓ^{+} ℓ^{-}$

Philipp Böer, Thorsten Feldmann, Danny van Dyk

We study the differential decay rate for the rare $Λ_{b} \to Λ (\to N π) ℓ^{+} ℓ^{-}$ transition, including a determination of the complete angular distribution, assuming unpolarized…
