In higher plants, the chloroplast NADH dehydrogenase-like complex (NDH) interacts with photosystem I (PSI) to form the NDH-PSI supercomplex via two minor light-harvesting complex I (LHCI) proteins, Lhca5 and Lhca6. Previously, we showed that in lhca5 and lhca6, NDH still associates with PSI to form smaller versions of the NDH-PSI supercomplex, although their molecular masses are far smaller tha...

Particle physics results of constant value and significant impact have been obtained at PSI, several efforts are presently ongoing expected to deliver new findings in the near future. In this special SciPost volume we collect them together a concise manner. Not yet included ideas for future facility upgrades or completely experimental efforts, but set extend years come.

Using a data sample of $\psi(3770)$ events collected with the BESIII detector at BEPCII corresponding to an integrated luminosity 2.9 fb$^{-1}$, we report measurement $\Lambda$ spin polarization in $e^+e^-\rightarrow\Lambda\bar\Lambda$ $\sqrt{s} = 3.773$ GeV. The significance is found be 2$\sigma$ including systematic uncertainty, which implies zero phase between transition amplitudes $\Lambda\...

Psi-calculi is a parametric framework for extensions of the pi-calculus; in earlier work we have explored their expressiveness and algebraic theory. In this paper we consider higher-order psi-calculi through a technically surprisingly simple extension of the framework, and show how an arbitrary psi-calculus can be lifted to its higher-order counterpart in a canonical way. We illustrate this wit...

The measurement of the pion–nucleon scattering lengths constitutes a high–precision test of the methods of Chiral Pertubation Theory (χPT), which is the low–energy approach of QCD. The πN s–wave scattering lengths are related to the strong–interaction shift ǫ1s and width Γ1s of the s–states of the pionic hydrogen atom. ǫ1s and Γ1s are determined from the measured energies and line widths of X–r...
