Species-wide inventory of organellar variation reveals ample phenotypic variation for photosynthetic performance.

Efforts to improve photosynthetic performance are increasingly employing natural genetic variation. However, genetic variation in the organellar genomes (plasmotypes) is often disregarded due to the difficulty of studying the plasmotypes and the lack of evidence that this is a worthwhile investment. Here, we systematically phenotyped plasmotype diversity using as a model species.

From pole parameters to line shapes and branching ratios.

Resonances are uniquely characterized by their complex pole locations and the corresponding residues. In practice, however, resonances are typically identified experimentally as structures in invariant mass distributions, with branching fractions of resonances determined as ratios of count rates. To make contact between these quantities it is necessary to connect line shapes and resonance parameters.

Role of Left-Hand Cut Contributions on Pole Extractions from Lattice Data: Case Study for T_{cc}(3875)^{+}.

We discuss recent lattice data for the T_{cc}(3875)^{+} state to stress, for the first time, a potentially strong impact of left-hand cuts from the one-pion exchange on the pole extraction for near-threshold exotic states. In particular, if the left-hand cut is located close to the two-particle threshold, which happens naturally in the DD^{*} system for the pion mass exceeding its physical value, the effective-range expansion is valid only in a very limited energy range up to the cut and as such is of little use to reliably extract the poles. Then, an accurate extraction of the pole locations requires the one-pion exchange to be implemented explicitly into the scattering amplitudes.

Addendum: A dispersive analysis of and .

In this addendum to Ref. [1] we show that the mismatch between the - mixing parameter as extracted from and can be resolved by including higher orders in the expansion in in the description of the decay. We repeat the analysis in this extended framework and update the numerical results accordingly.

A dispersive analysis of and .

We present a dispersive representation of the transition form factor that allows one to account, in a consistent way, for the effects of - mixing in both the isoscalar and the isovector contributions. Using this formalism, we analyze recent data on to constrain the isovector part of the form factor, individually and in combination with data for the pion vector form factor, which suggests a tension in the - mixing parameter. As a first application, we use our results, in combination with the most recent input for the isoscalar part of the form factor, to predict the corresponding spectrum of , in particular we find the slope parameter .
