Measurement of the Tensor-Analyzing Power Component T20 for Incoherent Negative Pion Photoproduction on a Deuteron Open
New results for the T20-component of the tensor-analyzing power of the incoherent negative pion photoproduction are presented. The experiment was performed for the electron beam energy of 800 MeV at the VEPP-3 storage ring in 2021. To extr…

Ambiguities in a partial-wave analysis of <i>γ</i> <i>p</i> → <i>π</i> <sup>0</sup> <i>p</i> with truncation in total angular momentum Open
We address some questions related to the discrete ambiguity problem in a truncated partial-wave analysis in the case when the helicity basis together with truncation in total angular momentum j is employed. As a numerical application, we c…

The SDSS-V Black Hole Mapper Reverberation Mapping Project: Unusual Broad-Line Variability in a Luminous Quasar Open
We present a high-cadence multi-epoch analysis of dramatic variability of three broad emission lines (MgII, H$β$, and H$α$) in the spectra of the luminous quasar ($λL_λ$(5100Å) = $4.7 \times 10^{44}$ erg s$^{-1}$) SDSS J141041.25+531849.0 …

Simplification of the complete-experiment problem for photoproduction of two pseudoscalar mesons on a nucleon in a truncated partial-wave analysis Open
It is shown that within a truncated partial wave analysis for photoproduction of two pseudoscalar mesons, it is possible to halve the number of independent partial amplitudes by taking into account parity conservation. In addition, within …
