Study of the decay Ds+→π+π+π−η and observation of the W -annihilation decay Ds+→a0(980)+ρ0

Mikhail N. Achasov, P. Adlarson, S. Ahmed, M. Albrecht et autres

The decay ${D}_{s}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}\ensuremath{\eta}$ is observed for the first time, using ${e}^{+}{e}^{\ensuremath{-}}$ collision data corresponding to an integrated luminosity of $6.32\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, collected by the BESIII detector at center-of-mass energies between 4.178 and 4.226 GeV. The absolute branching fraction for this decay …

New Features in the Electromagnetic Structure of the Neutron

Mikhail N. Achasov, X. Q. Hao, F. A. Harris, K. L. He et autres

Here we present new results for the Born cross section and the effective form factor of the neutron at the center-of-mass energies ${\\bf \\sqrt{s}}$ between 2.0 and 3.08 GeV, using 18 data sets corresponding to an integrated luminosity of 647.9 pb${\\bf ^{-1}}$ …
