Amplitude Analyses of D Decay Dalitz Plots

We describe Dalitz plots arising in studies of $D$-meson decays, and what we have learned from them in recent years. After some mention of technique and history, we focus on decay of the $D^\pm$ and $D_s^\pm$ mesons to the $K^-K^+\pi^\pm$ final state, and on $D_s^\pm$ decay to $\pi^+\pi^-\pi^\pm$. Some mention of other Dalitz plots involving $D$-meson decays is also made.Comment: To appear in the proceedings of The 5th International Workshop on Charm Physics (Charm 2012

Measurement of the branching fractions of the B+ -> eta l(+)nu(l) and B+ -> eta ' l(+)nu(l) decays with signal-side only reconstruction in the full q(2) range

The branching fractions of the decays B+ -> eta l(+)nu(l) and B+ -> eta'l(+)nu(l) are measured, where l is either an electron or a muon, using a data sample of 711 fb(-1) containing 772 x 10(6)B (B) over bar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. To reduce the dependence of the result on the form factor model, the measurement is performed over the entire q(2) range. The resulting branching fractions are B(B+ -> eta l(+)nu(l)) = (2.83 +/- 0.55((stat.)) +/- 0.34((syst.))) x 10(-5) and B(B+ -> eta'l(+)nu(l)) = (2.79 +/- 1.29((stat.)) +/- 0.30((syst.))) x 10(-5).journal articl

A Comment on the Implementation of the Strategy of Reinvigorating our Country through trained personnel in terms of Strategic Management

当今世界，以知识为主导、以高新技术及其产业为基础和支撑的知识经济已经悄然来临，世界范围内综合国力的竞争日趋激烈。这种竞争，说到底是人才的竞争，实质上就是人才战略的竞争。中国作为世界上最大的发展中国家，人口多，底子薄，人均资源相对不足，这一基本国情决定了中国的发展必须坚持“以人为本”，走人才强国之路。在2003年全国人才工作会议上，把实施人才强国战略作为科学发展观的有机组成部分，作为党和国家一项重大而紧迫的任务，作为新世纪新阶段国家人才工作的根本任务。“十一五”规划进一步提出了加快推进人才强国战略，为我国政治、经济、社会的发展提供智力支持。因此，在现阶段研究人才强国战略的实施具有重大的战略意义。...In our times, the knowledge economy that took knowledge as the leading factor, is based on new and high technology and industry. It has already come quietly. The competition of the comprehensive national strength is becoming fiercer and fiercer in the whole world. This kind of competition is talents' competition after all. It is a competition of the talents strategy in fact. As the largest develop...学位：管理学硕士院系专业：公共事务学院公共管理系_行政管理学号：20030603

The Case for a Muon Collider Higgs Factory

We propose the construction of a compact Muon Collider Higgs Factory. Such a machine can produce up to \sim 14,000 at 8\times 10^{31} cm^-2 sec^-1 clean Higgs events per year, enabling the most precise possible measurement of the mass, width and Higgs-Yukawa coupling constants.Comment: Supporting letter for the document: "Muon Collider Higgs Factory for Smowmass 2013", A White Paper submitted to the 2013 U.S. Community Summer Study of the Division of Particles and Fields of the American Physical Society, Y.

Precision Measurement of the Ratio Β(Y(3\u3ci\u3eS\u3c/i\u3e) → τ \u3csup\u3e+\u3c/sup\u3e τ\u3csup\u3e−\u3c/sup\u3e) / Β( Y(3\u3ci\u3eS\u3c/i\u3e)→ μ\u3csup\u3e+\u3c/sup\u3e μ\u3csup\u3e−

We report on a precision measurement of the ratio Rϒð3SÞ τμ ¼ Bðϒð3SÞ → τþτ−Þ=Bðϒð3SÞ → μþμ−Þ using data collected with the BABAR detector at the SLAC PEP-II eþe− collider. The measurement is based on a 28 fb−1 data sample collected at a center-of-mass energy of 10.355 GeV corresponding to a sample of 122 million ϒð3SÞ mesons. The ratio is measured to be Rϒð3SÞ τμ ¼ 0.966 0.008stat 0.014syst and is in agreement with the standard model prediction of 0.9948 within 2 standard deviations. The uncertainty in Rϒð3SÞ τμ is almost an order of magnitude smaller than the only previous measurement

Latent TB infection diagnosis in population exposed to TB subjects in close and poor ventilated high TB endemic zone in India.

The present study was designed to investigate the utility of Quantiferon TB gold (QFT-G) and Tuberculin skin test (TST) for diagnosis of latent TB infection (LTBI) in high crowding TB endemic zone of Nagpur, India and their comparison with associated risk factors.Out of 342 eligible participants, QFT-G and TST were performed in 162 participants.The prevalence of LTBI observed according to QFT-G and TST was 48% and 42% respectively, with an agreement of 52.47%. QFT-G positivity was associated with age while TST positivity was associated with body mass index (BMI). Duration of exposure emerged as a key risk factor significantly associated with both the tests.The prevalence of LTBI was quite high in the studied zone as detected by both the evaluated tests and thus, the combination of both the tests will be best predictive for LTBI in such high TB endemic regions
