项目摘要
"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."One of the strongest emphases in particle physics today is on searching for signals of "new physics", that is, physics beyond the Standard Model (SM). The next few years could witness important discoveries as the Large Hadron Collider (LHC) experimentalists map out physics at the TeV scale. Complementary searches for new physics (NP) are also underway at low energies, using indirect probes. Results from neutrino physics have already provided exciting hints regarding the structure of physics beyond the SM. Future neutrino experiments will continue to map out the masses, mixings and CP properties of neutrinos and to probe their essential nature (i.e., Majorana or Dirac). On another front, LHCb is expected to build on the precision B meson measurements made at Babar and Belle; a possible Super Flavor Factory could extend this reach, and would also make important contributions to tau and charm studies. Several of the low- and high-energy experiments are expected to employ CP-odd observables in the search for NP, since many extensions of the SM contain novel sources of CP violation. CP-odd observables can be useful discriminators between NP and SM effects; furthermore, such observables could help discern the structure of NP.The Principal Investigator will assess phenomenological effects of several extensions of the SM, concentrating on observables that are odd under CP. A complementary focus of the proposed work is expected to be the constraint, modification or generalization of various extensions of the SM. The proposed work will include emphases on both low- and high-energy processes. In the former case, the effects of new particles will be sought. In the latter, studies will be performed assuming that new particles could be produced on-shell in a collider environment. Specific projects include the calculation of rate asymmetries in chargino, stau and sbottom decays within supersymmetry, as well as investigations of top quark decays and certain B decays to vector-vector final states. Some of the broader impacts are that the proposed work will be useful to experimentalists as they begin to sift through large amounts of data searching for signals of NP.The direct involvement of several undergraduate students in the research will enhance the educational experiences of those students and will better prepare them for entrance into top graduate schools. The increased level of undergraduate research will also help the institution attract highly qualified undergraduate students to the physics program and will be particularly helpful in attracting more female and minority students, who are currently underrepresented in the physics program at Taylor.
“该奖项是根据2009年美国复苏和再投资法案(公法111-5)资助的。“当今粒子物理学的最大重点之一是寻找“新物理学”的信号,即超越标准模型(SM)的物理学。 在接下来的几年里,随着大型强子对撞机(LHC)实验学家在TeV尺度上绘制出物理学的重要发现。对新物理学(NP)的补充研究也在低能量下进行,使用间接探针。中微子物理学的结果已经为超越SM的物理结构提供了令人兴奋的线索。未来的中微子实验将继续绘制中微子的质量、混合和CP性质,并探测它们的本质(即,Majorana或Dirac)。另一方面,大型强子对撞机B有望建立在巴巴尔和贝儿的精确B介子测量的基础上;一个可能的超级味道工厂可以扩大这一范围,也将为τ和粲的研究做出重要贡献。一些低能量和高能量的实验预计将采用CP-奇观测量在搜索NP,因为许多扩展的SM包含新的CP违反的来源。CP-奇观测值可以是NP和SM效应之间的有用判别器;此外,这样的观测值可以帮助辨别NP的结构。首席研究员将评估SM的几个扩展的现象学效应,集中在CP下的奇观测值。一个互补的重点,拟议的工作预计将是限制,修改或推广的各种扩展的SM。拟议的工作将包括对低能量和高能量过程的强调。在前一种情况下,将寻求新粒子的影响。在后者中,将假设在对撞机环境中可以在壳层上产生新粒子来进行研究。具体项目包括计算超对称性中的chargino,stau和sbottom衰变的速率不对称性,以及研究顶夸克衰变和某些B衰变到矢量-矢量最终状态。一些更广泛的影响是,拟议的工作将是有用的实验,因为他们开始筛选通过大量的数据搜索信号的NP。直接参与研究的几个本科生将提高这些学生的教育经验,并将更好地准备他们进入顶尖的研究生院。本科研究水平的提高也将有助于该机构吸引高素质的本科生到物理课程,并将特别有助于吸引更多的女性和少数民族学生,谁是目前在泰勒的物理课程代表性不足。
