The Minimal Higgsless Model predicts the existence of new vector gauge boson W1^±, By the process PP →W1^±qq →W^±Z^0qq, Z^0→ 1^+1^-, W^±→ qq (1=e,μ; q is hadronized to be jets), we study the sensitivity of searching for this possible vector gauge boson in the level of generator events of signal and backgrounds, then give integrated luminosity required to discover 5σ signal as a function of W1^± mass. The generator for the signal PP → W1^±qq →W^±Z^0qq at tree level is developed with the Minimal Higgsless Model and then interfaced with PYTHIA for the patton showers and hadronization. The backgrounds are produced with MadGraph and PYTHIA. 相似文献

We clarify the difference among potential models so far proposed to explain mass spectra of heavylight mesons via transformations of the vacuum.Applying our idea to QQ quarkonium,we obtain the extra term,1/r ^2 with positive coefficient,other than non-relativistic potential terms expected for quarkonium. 相似文献

Without the non-relativistic approximation in one-loop function, the dominating one-loop contribution to the quark-antiquark potential is studied numerically in terms of perturbative Quantum Chromo Dynamics (QCD). For Coulomb-like potential, the ratio of the one-loop correction to the tree diagram contribution is presented, whose absolute value is about 20%. Our result is consistent with the analysis that the one-loop contribution should be suppressed by a factor αs/π to the leading order contribution. This work can deepen the comprehension of αs in Cornel potential. 相似文献

建立了资本市场跳跃检测的数理方法,并用高频数据对上海综指和上海证券市场不同板块八只股票的跳跃情况进行了实证检测.首先,将资本市场的跳跃分为泊松跳跃和列维跳跃,推导和证明了泊松跳跃和列维跳跃检测的统计量.以此理论为基础,再对中国证券市场的泊松跳跃和列维跳跃检测情况进行了实证研究.研究发现:上证综指收益率跳跃比率和其他八只股票收益率跳跃比率相比是最小的;列维跳跃的强度明显高于泊松跳跃的强度.所建立的检测统计量能具体定位哪一个收益率包含泊松跳跃或列维跳跃,具有一定的创新性. 相似文献

依托智慧树平台,结合已有的MOOC教学视频资源,并以QQ群为辅助交流工具,构建了普通化学在线课程。普通化学的2条主线中,物质的微观结构起着至关重要的作用,决定着物质的微观和宏观性质。以“原子的电子层结构”为教学案例,利用智慧树大数据平台的信息支持和互动交流功能,对学生“直播课前-课中-课后”3个学习环节和“直播互动、章测验和期末考试”3个教学效果反馈环节进行了实时跟踪与分析。希望在线教学中积累的经验能为线上线下混合式化学教学改革提供参考。 相似文献
