“…Unfortunately, no B i → B f ν ν decays have been searched for experimentally so far. As an example, assuming that the decay Σ + → pν ν is dominated by the short-distance contribution, one can make an estimation based on the following relation [39,40]:…”

The study of hyperon decays at the Beijing Electron Spectrometer III (BESIII) is proposed to investigate the events of $J/\psi$ decay into hyperon pairs, which provide a pristine experimental environment at the Beijing Electron--Positron Collider II. About $10^{6}$--$10^8$ hyperons, i.e., $\Lambda$, $\Sigma$, $\Xi$, and $\Omega$, will be produced in the $J/\psi$ and $\psi(2S)$ decays with the proposed data samples at BESIII. Based on these samples, the measurement sensitivity of the branching fractions of the hyperon decays is in the range of $10^{-5}$--$10^{-8}$. In addition, with the known center-of-mass energy and "tag technique," rare decays and decays with invisible final states can be probed.Comment: 8 pages, 8 tables, add more references and corrections; many typos fixe

“…Thus, in the SM, one can estimate the branching fraction to be B(Σ + → pν ν) ∼ 5×10 −13 by considering the lifetime difference between Σ + and Σ − and isospin rotation [39]. Obviously, BESIII cannot reach a sensitivity of 10 −13 .…”

“…e study was based on the authors' assumption, and it is not applicable now. Feng et al evaluated the performance of purchase restriction policy in Shanghai by comparing the vehicle stock in Shanghai with three similar areas [30]. e results indicated that the annual growth rate of private car ownership had dropped by 30% since 2003.…”

With the improvement of living standards, the demand for residents’ travel has grown rapidly. At present, China has surpassed the U.S. to become the world’s largest vehicle sales country. By the end of 2018, there had been over 200 million private passenger cars in China. Meanwhile, the increase in the number of cars has also brought a series of other problems: energy consumption, air pollution, traffic congestion, etc. Therefore, some first-tier cities have successively introduced motor vehicle purchase restriction policies to constrain the surge of local private cars. However, existing researches have overemphasized the factors that promote the development of China’s motor vehicle market and ignored the importance of the purchase restriction policies. In this study, policies in Beijing, Tianjin, Shanghai, and Guangzhou are introduced, and their impacts on local private passenger car stock are analyzed. The results indicate that purchase restriction policies kept the car ownership per thousand people in these cities in a relatively stable level with growing economy. Therefore, as the number of cities with restriction policies increases, it is necessary to take those policies into consideration in the forecast of possession. Meanwhile, the local governments should still think over policy contents from more aspects, like number of issued plates every year, special measures for new energy vehicles, and travel demand of residents.
