Electroweak Processes at NLO and NNLO Level

最近来自中微子振荡、暗物质和暗能量的证据表明，已有40年历史的粒子物理标准模型是不完整的，我们正处在一个新理论和“新物理学”的门槛上。寻找新物理可能信号的一种方法是在低能量下进行高精度实验，这可以间接获得多tev尺度的物理，并对大型强子对撞机研究计划起重要的补充作用。这项研究需要实验和理论两方面的努力，而新一代的实验将需要理论上新的精确度。******在这个研究项目中，我们努力将亚原子物理计算提升到一个新的水平，并利用新的半自动化符号计算方法为高精度实验提供最精确和可靠的理论输入。我们创新的计算模型可用于广泛的应用，包括轻子-轻子和轻子-强子散射的次领先和次领先电弱辐射校正，模拟介子电产生，以及评估强子的电和磁动态极化。该计划还将培养新一代科学家，使加拿大在未来几十年保持其在世界级研究领域的前沿地位

Recent evidence coming from neutrino oscillation, dark matter and dark energy shows that the 40-year old Standard Model of Particle Physics incomplete, and that we are at the threshold of a new theory and “New Physics.” One way to look for possible signals of new physics is with high-precision experiments at lower energy which can provide indirect access to physics at multi-TeV scales and play an important complementary role to the Large Hadron Collider research program. This research requires both experimental and theoretical effort, and the new-generation experiments will need a new degree of precision from theory. ****** In this research program, we strive to bring subatomic physics computations to the next level and to provide the most precise and reliable theoretical input for the high-precision experiments by taking advantage of the new semi-automated symbolic computing methods. Our innovative computational models can be used for a wide range of applications, including next-to-leading and next-to-next-to-leading electroweak radiative corrections for lepton-lepton and lepton-hadron scattering, modeling pion electroproduction, and evaluating electric and magnetic dynamical polarizabilities for hadrons. The program will also allow for training a new generation of scientists enabling Canada to maintain its position at the forefront of world-class research for decades to come.***
