I was recently hired as an ATLAS-Canada faculty member at Carleton University, starting January 2016. This is an application for a bridging grant intended to support my research program for two years until the renewal of the ATLAS-Canada Project grant in April 2018, which I will take part in. My proposed research program will enhance Canada's role in one of the world's most highly regarded scientific endeavours. With the Large Hadron Collider (LHC) we study the fundamental nature of our world, including both the elementary building blocks of matter and the forces of the Universe. The LHC produces the highest energy collisions of any facility in the world, and can reproduce particle collisions which mimic the conditions of the Universe a fraction of a second after the Big Bang. ATLAS is one of the detectors constructed at the LHC and records the resulting collisions. By studying these collisions, we learn about the origin and evolution of the Universe, and the laws of Nature. The primary objective of my research program is to perform precise studies of the recently discovered Higgs boson: the elementary particle that play a key role in how other particles obtain mass. During the past five years, I have been heavily involved at the forefront of this effort and I will continue these efforts as a professor at Carleton University. During the term of the proposed research, the LHC will deliver a very large dataset that makes it possible to significantly extend our knowledge about the Higgs boson. I plan to measure the overall production rate as well as kinematic, production and decay properties of the Higgs boson, and to interpret these results to look for evidence of physics Beyond the Standard Model. A second topic of my research program is to join the ATLAS-Canada effort with the design, production and characterization of the ATLAS inner tracker (ITk) detector upgrade that will be installed in 2024 prior to the start of the "High Luminosity LHC" (HL-LHC). This detector needs to be highly performant in the very harsh environment of the HL-LHC and I will contribute with my expertise in simulations to evaluate the gain from different design scenarios (2016) and contribute to the testing of the first ITk silicon modules from the pre-production in 2017. I request funding to form a small research team consisting of one research associate and two graduate students for the period April 2016 to April 2018. The funding is intended to cover salaries, field work at CERN, conference attendance and personal computers. A very important aspect of the research project is training of the personnel. Important skills to be developed include advanced data analysis techniques, effective international collaboration, and experience with and understanding of cutting-edge technology. These skills are applicable not only to physics research, but also to many other fields such as medical physics, finance and predictive analysis (“big data”).

我最近被聘为卡尔顿大学的ATLAS-加拿大教师，从2016年1月开始。这是一份旨在支持我的研究计划两年的过渡补助金申请，直到2018年4月ATLAS-加拿大项目补助金更新，我将参加。我提出的研究计划将加强加拿大在世界上最受推崇的科学努力之一中的作用。 利用大型强子对撞机（LHC），我们研究我们世界的基本性质，包括物质的基本组成部分和宇宙的力量。LHC产生世界上任何设施中能量最高的碰撞，并且可以再现粒子碰撞，模拟宇宙大爆炸后几分之一秒的条件。ATLAS是在LHC上建造的探测器之一，并记录了由此产生的碰撞。通过研究这些碰撞，我们了解宇宙的起源和演化，以及自然规律。 我的研究计划的主要目标是对最近发现的希格斯玻色子进行精确的研究：这种基本粒子在其他粒子如何获得质量方面发挥着关键作用。在过去的五年里，我一直积极参与这项工作的最前沿，我将继续这些努力作为卡尔顿大学的教授。在拟议的研究期间，LHC将提供一个非常大的数据集，使我们有可能显着扩展我们对希格斯玻色子的知识。我计划测量希格斯玻色子的整体产生速率以及运动学，产生和衰变特性，并解释这些结果，以寻找超越标准模型的物理学证据。 我的研究计划的第二个主题是加入ATLAS-加拿大的工作，设计，生产和表征ATLAS内部跟踪器（ITk）探测器升级，将于2024年在“高亮度LHC”（HL-LHC）开始之前安装。该探测器需要在HL-LHC非常恶劣的环境中具有高性能，我将利用我在模拟方面的专业知识来评估不同设计方案的增益（2016年），并为2017年预生产的第一批ITk硅模块的测试做出贡献。 我请求资助成立一个小型研究团队，由一名研究助理和两名研究生组成，任期为2016年4月至2018年4月。这笔资金用于支付薪金、欧洲核子研究组织的实地工作、出席会议和个人计算机。研究项目的一个非常重要的方面是人员的培训。需要培养的重要技能包括先进的数据分析技术、有效的国际合作以及对尖端技术的了解和经验。这些技能不仅适用于物理学研究，也适用于许多其他领域，如医学物理学，金融和预测分析（“大数据”）。
