TL;DR: A brief description of the SLAC and KEK B Factories as well as their detectors, BaBar and Belle, and data taking related issues can be found in Part A of this book as mentioned in this paper.
Abstract: This work is on the Physics of the B Factories. Part A of this book contains a brief description of the SLAC and KEK B Factories as well as their detectors, BaBar and Belle, and data taking related issues. Part B discusses tools and methods used by the experiments in order to obtain results. The results themselves can be found in Part C.
Please note that version 3 on the archive is the auxiliary version of the Physics of the B Factories book. This uses the notation alpha, beta, gamma for the angles of the Unitarity Triangle. The nominal version uses the notation phi_1, phi_2 and phi_3. Please cite this work as Eur. Phys. J. C74 (2014) 3026.

TL;DR: In this paper, the process of the VEPP-2000 collider with the SND detector in the energy range from threshold up to 2 GeV has been studied at the collider and the cross section and effective neutron form factor have been measured.
Abstract: The process ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}n\overline{n}$ has been studied at the VEPP-2000 ${e}^{+}{e}^{\ensuremath{-}}$ collider with the SND detector in the energy range from threshold up to 2 GeV. As a result of the experiment, the ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}n\overline{n}$ cross section and effective neutron form factor have been measured.

TL;DR: In this article, the authors measured the center-of-mass energy range 1.07-2.00 GeV using the decay mode of the SND detector at the VEPP-2000 collider.
Abstract: The $e^+e^-\to\eta\gamma$ cross section has been measured in the center-of-mass energy range 1.07--2.00 GeV using the decay mode $\eta\to 3\pi^0$, $\pi^0\to \gamma\gamma$. The analysis is based on 36 pb$^{-1}$ of integrated luminosity collected with the SND detector at the VEPP-2000 $e^+e^-$ collider. The measured cross section of about 35 pb at 1.5 GeV is explained by decays of the $\rho(1450)$ and $\phi(1680)$ resonances.

TL;DR: In this article, it was shown that the BABAR detector at the PEP-II collider at the SLAC National Accelerator Laboratory can detect the decay of the $B$ meson to the charmless vector-vector final states.
Abstract: We describe searches for $B$ meson decays to the charmless vector-vector final states $\ensuremath{\omega}\ensuremath{\omega}$ and $\ensuremath{\omega}\ensuremath{\phi}$ with $471\ifmmode\times\else\texttimes\fi{}1{0}^{6}B\overline{B}$ pairs produced in ${e}^{+}{e}^{\ensuremath{-}}$ annihilation at $\sqrt{s}=10.58\text{ }\text{ }\mathrm{GeV}$ using the BABAR detector at the PEP-II collider at the SLAC National Accelerator Laboratory. We measure the branching fraction $\mathcal{B}({B}^{0}\ensuremath{\rightarrow}\ensuremath{\omega}\ensuremath{\omega})=(1.2\ifmmode\pm\else\textpm\fi{}{0.3}_{\ensuremath{-}0.2}^{+0.3})\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}6}$, where the first uncertainty is statistical and the second is systematic, corresponding to a significance of 4.4 standard deviations. We also determine the upper limit $\mathcal{B}({B}^{0}\ensuremath{\rightarrow}\ensuremath{\omega}\ensuremath{\phi})l0.7\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}6}$ at 90% confidence level. These measurements provide the first evidence for the decay ${B}^{0}\ensuremath{\rightarrow}\ensuremath{\omega}\ensuremath{\omega}$, and an improvement of the upper limit for the decay ${B}^{0}\ensuremath{\rightarrow}\ensuremath{\omega}\ensuremath{\phi}$.
