TL;DR: In this article, the authors report evidence for the production of a new narrow charged state in e/sup +/e/sup -/ annihilation at a center-of-mass energy of 4.03 GeV.
Abstract: We report evidence for the production of a new narrow charged state in e/sup +/e/sup -/ annihilation at a center-of-mass energy of 4.03 GeV. This state, which has a mass of 1876 +- 15 MeV/c/sup 2/, is observed in the exotic channel Kminus-or-plus..pi../sup plus-or-minus/..pi.. +- , but not in the nonexotic channel Kminus-or-plus..pi../sup +/..pi../sup -/. It is produced primarily in association with a system of mass 2.01 +- 0.02 GeV/c/sup 2/. These characteristics are just those expected of a charged charmed meson. (AIP)

TL;DR: In this article, TTF-TCNQ was measured along the $b$ axis of tetrathiafulvalenium-tetracyanoquinodimethanide (TTF-TTE) to provide a comprehensive summary including approximately 600 samples studied at 18 different laboratories.
Abstract: New measurements of electrical conductivity along the $b$ axis of tetrathiafulvalenium-tetracyanoquinodimethanide (TTF-TCNQ) are combined with published results to provide a comprehensive summary including approximately 600 samples studied at 18 different laboratories The magnitudes of these measured conductivities do not necessitate the assumption of superconducting fluctuations or any other collective state in which the conductivity exceeds the limitations of single-particle scattering Since an adequate theory of the limitations of single-particle scattering for TTF-TCNQ does not exist at present, experiment alone does not rule out the possibility that collective effects may somewhat enhance or suppress the conductivity

TL;DR: In this article, the authors present the inclusive photon spectra observed in the decay sequence of the photon in the form of a branching fraction of 0.026 with masses of 3504, 3543, and 3455 or 3340 MeV.
Abstract: We present the inclusive photon spectra observed in $\ensuremath{\psi}(3095)$ and $\ensuremath{\psi}(3684)$ decays. The decay $\ensuremath{\psi}(3684)\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\chi}(3415)$ is observed with a branching fraction of 0.075 \ifmmode\pm\else\textpm\fi{} 0.026. Evidence is presented for three intermediate states in the decay sequence $\ensuremath{\psi}(3684)\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}\ensuremath{\psi}(3095)$ with masses of 3504, 3543, and 3455 or 3340 MeV.

TL;DR: From this study, the isospin and G-parity quantum numbers are found to be I/supG/=0$sup -$.
Abstract: We present here a measurement of six branching ratios of psi (3095) corresponding to the decays psi (3095) $Yields$rho$pi$, 2($pi$$sup +$$pi$$sup - $), 2($pi$$sup +$$pi$$sup -$)1$pi$$sup 0$, 3($pi$$sup +$$pi$$sup -$), 3($pi$$sup +$$pi$$sup -$)1$pi$$sup 0$, and 4($pi$$sup +$$pi$$sup -$)1$pi$$sup 0$. From this study, the isospin and G-parity quantum numbers are found to be I/supG/=0$sup -$. (AIP)

TL;DR: In this paper, it was shown that isospin is conserved in the decay of the decay psi (3684)..-->..psi (3095)..pi pi.
Abstract: The decay psi (3684) ..-->..psi (3095) eta has been observed to have a branching fraction of (4.3+-0.8) %. This measurement, together with previous measurements of psi (3684) ..-->..psi (3095)+ anything, psi (3684) ..-->..psi (3095) ..pi../sup +/..pi../sup -/, and psi (3684) ..-->..psi (3095) ..gamma gamma.., indicates that isospin is conserved in the decay psi (3684) ..-->..psi (3095) ..pi pi.. and establishes the isospin and G parity of the psi (3684) to be I/subG/=0/sup -/.
