The CERN Large Hadron Collider (LHC) has the highest direct energy reach of any particle physics facility, and Canada's central role in the ATLAS collaboration at the LHC will keep us at the forefront of international particle physics. ATLAS and the LHC conducted our first major operational period, called Run 1, in 2011 and 2012, with proton-proton collision centre-of-mass energies of 7-8 TeV. With those data, ATLAS, together with the CMS collaboration, discovered the Higgs boson whose existence was predicted in 1964 and intensely sought over the intervening half century. The Higgs discovery was covered widely by International and Canadian media and led directly to the award of the 2013 Nobel prize in physics to Peter Higgs and Francois Englert. Studies of the properties of the newly observed Higgs particle have so far shown it to be consistent with the Standard Model Higgs, but the limited number of Higgs particles observed at the LHC restrict the sensitivity of the results. Canadians played leading roles in several of the analyses used to discover the Higgs boson and to measure its properties, including the current coordination of the ATLAS Higgs working group. The Higgs boson discovery was a remarkable achievement, but only scratches the surface of the potential physics reach of ATLAS and the LHC, which were designed from the outset to probe for signatures of new physics at the TeV scale that could "stabilize" the vacuum and address deficiencies of the Standard Model. Achieving the full potential of ATLAS requires more data at higher energies.

CERN大型强子对撞机（LHC）具有任何粒子物理设施的最高直接能量范围，而加拿大在LHC的ATLAS合作中的核心作用将使我们处于国际粒子物理学的最前沿。 Atlas和LHC在2011年和2012年进行了我们的第一个主要运营时期，称为Run 1，Proton-Proton Collison Collison Collision Centre Centre Mass Energies为7-8 TEV。通过这些数据，Atlas与CMS合作一起发现了Higgs Boson的存在，其存在于1964年被预测，并且在半个世纪的中期确实受到了伤害。希格斯发现被国际和加拿大媒体广泛涵盖，并直接授予彼得·希格斯和弗朗索瓦·恩格勒特奖。到目前为止，对新观察到的希格斯粒子的性质的研究表明，它与标准模型HIGG是一致的，但是在LHC处观察到的有限数量的HigGS颗粒限制了结果的敏感性。加拿大人在用于发现希格斯玻色子的几项分析中扮演了领导角色，并测量其特性，包括当前的Atlas Higgs工作组的协调。希格斯玻色子发现是一项了不起的成就，但仅刮擦了Atlas和LHC的潜在物理范围的表面，从一开始就设计到可以在TEV量表上探测新物理学的签名，以“稳定”真空稳定并解决标准模型的缺陷。达到地图集的全部潜力需要更高能量的更多数据。
