In this study,the heavy to heavy decay of B0s → D*+D-is evaluated through the factorization approach by using the final state interaction as an effective correction.Under the factorization approach,this decay mode oc-curs only through the annihilation process,so a small amount is produced.Feynman\'s rules state that six meson pairs can be assumed for the intermediate states before the final meson pairs are produced.By taking into account the ef-fects of twelve final state interaction diagrams in the calculations,a significant correction is obtained.These effects correct the value of the branching ratio obtained by the pure factorization approach from (2.41 ± 1.37) × 10-5 to(8.27 ± 2.23) × 10-5.The value obtained for the branching ratio of the B0s → D*+D-decay is consistent with the ex-perimental results.

高职《大学语文》作为公共必修课之一,往往因合班教学,人数较多,教师很难做到因材施教.同时又因学生不够重视,导致学习积极性不高,教学效果欠佳.互联网为我们提供了丰富的知识获取途径,也为学生提供了多种“走神”的方式,如何利用网络搭建“多平台互动”的教学模式,增强学生“输入知识”的效率,提高教学效果,激发学生学习兴趣、调动学生学习主动性.通过改变传统授课模式提升人才培养质量,即为该文尝试研究的核心问题.
Within our aim to clarify some aspects of the breakup dynamics of loosely-bound neutron-halo pro-jectiles on a heavy target,we apply the continuum discretized coupled-channel formalism to investigate the berylli-um 11Be breakup on a lead 208Pb target at E
随着经济的发展和时代的进步,就业竞争也变得越来越激烈,当代大学生的就业压力也在随之不断加大.据相关研究表明职业社会支持对大学生的职业适应和就业能力有正向影响,大学生职业适应与职业社会化之间存在中介关系,所以需要不断提高大学生的就业能力.此外,积极主动的人格在职业适应和就业能力之间具有调节作用.更具体地说,更高积极性人格水平增强了职业适应能力.所以大学生的就业能力是多方面决定的,需要进行综合考量.
The deformation and associated optimum/uniquely fixed orientations play an important role in the syn-thesis of compound nuclei via cold and hot fusion reactions,respectively,at the lowest and highest barrier energies.The choice of optimum orientation (θop
随着我国教育体制的深化改革,教育部门对各级院校提出了全新的教学要求,避免出现“水课”“拖课”等现象,并根据实际情况为学生打造出了“金课”课堂.但是现阶段我国部分高校在建设“金课”课堂过程中还存在一定的问题,缺乏行之有效的参考文献,部分教师教学态度并不是十分端正,导致学生学习效率下降,无法调动学生学习积极性.基于此,笔者结合自身实际“金课”课堂开设经验,对“金课”课堂建设因素进行分析,分析部分高校教师建设“金课”课堂过程中存在的问题,在以评促建视角下提出具有建设意义的教学优化策略.
It is known that elastic magnetic electron scattering can be used to study the magnetic properties of nuc-lei and determine the outermost-shell single-particle orbitals.In this study,the magnetic form factors |FM(q)|2 of odd-A nuclei calculated with relat
The chiral magnetic effect (CME) is a novel transport phenomenon,arising from the interplay between quantum anomalies and strong magnetic fields in chiral systems.In high-energy nuclear collisions,the CME may survive the expansion of the quark-gluon plasm
酒的历史悠久,其蕴含的酒文化博大精深.该文以中国白酒和西方鸡尾酒为研究对象,比较中西方饮酒礼仪、酒器及社交等方面的差异,并在此基础上分析产生差异化的深层原因,即不同社会文化对各自的影响,以期为中国白酒走向世界和中国酒文化的推广提供新视角.
In order to confirm the existence of the dibaryon state d*(2380) observed at WASA@COSY,we estim-ate the cross section for production of the possible dibaryon and anti-dibaryon pair d*(d)* in the energy region of the upcoming experiments at (P)anda.Based o
In the contact interaction model,the quark propagator has only one solution,namely,the chiral sym-metry breaking solution,at vanishing temperature and density in the case of physical quark mass.We generalize the condensate feedback onto the coupling stren
