perturbative and nonperturbative corrections to polarized semileptonic decay distributions

Martin Fischer, Stefan Groote

In this paper we calculate first order radiative QCD corrections to the decay process 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 lattice QCD computation of two- and three- scattering quantities that includes an ensemble at the physical point. We study the quark mass d…

The -resonance with physical pion mass from 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…

-odd correlations in polarized top quark decays in the sequential decay and in the quasi three-body decay

M. Fischer, S. Groote, J. G. Körner

We identify the -odd structure functions that appear in the description of polarized top quark decays in the sequential decay (two…

Semi-inclusive decays Lambda_b -> X_c + D_s^* at O(alpha_s) including Lambda_b and D_s^* polarization effects

M. Fischer, S. Groote, J. G. Körner +1

In the leading order of the (1/m_b)-expansion in HQET the dominant contribution to the semi-inclusive decays of polarized Lambda_b baryons into the charm-strangeness mesons D_s and…

Leptonic - and -decays: mass effects, polarization effects and radiative corrections

M. Fischer, S. Groote, J. G. Körner +1

We calculate the radiative corrections to the unpolarized and the four polarized spectrum and rate functions in the leptonic decay of a polarized into a polarized electron. Th…

Complete angular analysis of polarized top decay at O(alpha_s)

M. Fischer, S. Groote, J. G. Körner +1

We calculate the O(alpha_s) radiative corrections to the three spin independent and five spin dependent structure functions that describe the angular decay distribution in the deca…

Longitudinal, transverse-plus and transverse-minus W-bosons in unpolarized top quark decays at O(alpha_s)

M. Fischer, S. Groote, J. G. Körner +1

We consider the O(alpha_s) radiative corrections to the decay of an unpolarized top quark into a bottom quark and a W-gauge boson where the helicities of the W are specified as lon…

Inclusive Decays of B Mesons into D_s and at Including Polarization Effects

M. Fischer, S. Groote, J. G. Körner +1

The dominant contribution to the inclusive decays of mesons into the charm-strangeness mesons and is expected to be given by the partonic process $b \to c+(D…

Polarized top decay into polarized W: t(up)->W(up) + b at O(alpha_s)

M. Fischer, S. Groote, J. G. Körner +2

We consider the decay of a polarized top quark into a polarized W-boson plus a bottom quark, followed by the decay of the W-boson into a pair of leptons or quarks. The polar angle…
