In the 1980s, Commerzbank was increasingly forced to become much more international if it wanted to be perceived as a relevant player in the field of investment banking, which was considered particularly attractive. This article focuses on the bank�

Measurement of the presence of $\mathrm{a}_1(1420)$ and $\omega(782)$ in $\tau^-\to\pi^-\pi^-\pi^+\nu_\tau$ at Belle

Autor: Rabusov, Andrei, Greenwald, Daniel, Paul, Stephan

We present preliminary results of a partial-wave analysis of $\tau^-\to\pi^-\pi^-\pi^+\nu_\tau$ using data from the Belle experiment at the KEKB $\mathrm{e}^+\mathrm{e}^-$ collider. We validate our model with a model-independent analysis. We see the

Measuring the Electric and Magnetic Form Factors of Protons and Antiprotons at small $Q^2$ and the charge radii of hadrons

Autor: Paul, Stephan

Charge radii of hadrons are back in the focus since precision spectroscopic measurements in muonic hydrogen revealed a proton charge radius considerably smaller than generally accepted ever since R.~Hofstaedter's pioneering experiments. Recent experi

In addition to the common 3-body decay of the neutron n → pe-ν̅e there should exist an effective 2-body subset with the electron and proton forming a Hydrogen bound state with well defined total momentum, total spin and magnetic quantum numbers.
