$O (α_{s})$ perturbative and nonperturbative corrections to polarized semileptonic $Λ_{b}$ decay distributions

Martin Fischer, Stefan Groote

In this paper we calculate first order radiative QCD corrections to the decay process $b \to c W^{-} (\to ℓ^{-} ν ˉ_{ℓ})$ of a polarized bottom quark. Taking into account both the bot…

Scattering of two and three physical pions at maximal isospin from lattice QCD

Matthias Fischer, Bartosz Kostrzewa, Liuming Liu +3

We present the first direct $N_{f} = 2$ lattice QCD computation of two- and three- $π^{+}$ scattering quantities that includes an ensemble at the physical point. We study the quark mass d…

The $ρ$ -resonance with physical pion mass from $N_{f} = 2$ lattice QCD

Matthias Fischer, Bartosz Kostrzewa, Maxim Mai +5

We present the first-ever lattice computation of pi pi-scattering in the I=1 channel with Nf=2 dynamical quark flavours obtained including an ensemble with physical value of the pi…

$T$ -odd correlations in polarized top quark decays in the sequential decay $t (↑) \to X_{b} + W^{+} (\to ℓ^{+} + ν_{ℓ})$ and in the quasi three-body decay $t (↑) \to X_{b} + ℓ^{+} + ν_{ℓ}$

M. Fischer, S. Groote, J. G. Körner

We identify the $T$ -odd structure functions that appear in the description of polarized top quark decays in the sequential decay $t (↑) \to X_{b} + W^{+} (\to ℓ^{+} + ν_{ℓ})$ (two…
