Charge symmetry breaking in $\hat{I}›$ hypernuclei: updated HYP 2015 progress report

Abstract

Ongoing progress in understanding and evaluating charge symmetry breaking in $\hat{I}›$ hypernuclei is discussed in connection to recent measurements of the ${}_{\hat{I}}{›}^4\mathrm{H}(0_{g.s.}^{+})$ binding energy at MAMI [A1 Collaboration: PRL 114 (2015) 232501] and of the ${}_{\hat{I}}{›}^4\mathrm{He}(1_{\mathrm{exc}}^{+})$ excitation energy at J-PARC [E13 Collaboration: PRL 115 (2015) 222501].
