This article is a highlight of the paper by Jarvi et al. in this issue of Photochemistry and Photobiology as well as a brief overview of the state of the field of singlet-oxygen ((1) O(2) ) detection in vivo. The in vivo detection of (1) O(2) using its characteristic 1270 nm phosphorescence is technically challenging. Nevertheless, substantial progress has been made in this area. Major advances...

Odderon induced contributions to exclusive photoproduction of π • , f 2 (1270) and a 2 (1320) have been searched for at HERA, using the multiphoton decays of these mesons. No indication for such contributions was found, in a kinematic region defined by the average photon-proton centre-of-mass energy W = 200 − 215 GeV, photon virtual-ities Q 2 < 0.01 GeV 2 and 0.02 GeV 2 < |t| < 0.3 GeV 2 , wher...

We calculate partial widths of the γγ decay of the tensor qq̄ states a2(1320), f2(1270), f2(1525), their radial excitations a2(1660), f2(1640), f2(1800) as well as F2qq̄ states. Calculations are performed in the framework of the same approach which was used before for the study of radiative decays f0(980) → γγ, a0(980) → γγ and φ(1020) → γf0(980): the assumption made is that of qq̄ structure of f0...

iaceae), widely distributed in South-east Asia, especially in most areas of China, and first recorded in “shengnong Bengcaojing” (early in the third century B.C.), has been used in traditional Chinese medicine to treat inflammatory and cardiovascular diseases for thousands of years. Chemical studies have shown that this plant mainly includes saponins, polysaccharide and homoisoflavonoidal compo...

In this work we study the strong decays of $\phi(2170)$ to final states involving kaonic resonances $K(1460)$, $K_1(1270)$ and $K_1(1400)$, on which experimental data have recently been extracted by BESIII Collaboration. The formalism developed here is based interpreting $K(1460)$ as arising from three-hadron dynamics, inspired our earlier works. For $K_1(1400)$ investigate different descriptio...
