洲核子研究大型子撞配的探器,ATLAS(A Toroidal LHC Apparatus:大型子撞)及CMS(Compact Muon Solenoid:型μ介子螺管)的共同研究,使用了大型子撞第二次期四年作(LHC Run 2)的完整集,得此交互作用的新洞察力。
1. ATLAS及CMS的核粒子生成,示希格斯玻色子夸克一起被生。 (援用自原文)
Recent years have seen the study of the Higgs boson progress from the discovery age to the measurement age. Among the latest studies of the properties of this unique particle by the ATLAS and CMS collaborations are measurements that shed further light on its interaction with top quarks – which, as the heaviest elementary particle, have the strongest interactions with the Higgs boson.
近年已看希格斯玻色子的研究,年代展到量年代。最近由ATLAS及CMS共同研究行之此特粒子性的研究中,包括多步明,其夸克交互作用的定。身最重基本粒子的夸克,具有希格斯玻色子最的交互作用。
In addition to allowing a determination of the strength of the top-Higgs interaction, the analyses open a new window on charge-parity (CP) violation.
除了使人得以,夸克希格斯玻色子交互作用的度之外,此些分析也了,有反荷奇偶性(CP)的新窗。
Discovered unexpectedly more than 50 years ago, CP violation reveals a fundamental asymmetry in nature that causes rare differences in the rates of processes involving matter particles and their antimatter counterparts, and is therefore thought to be an essential ingredient to explaining the observed abundance of matter over antimatter in the universe.
五十多年前,反荷奇偶性意外被。揭露了自然界中致,在涉及物粒子其反物物化程之速率中,出罕差的一基本不。
While the Standard Model of particle physics can explain CP violation, the amount of CP violation observed so far in experiments – recently in the behaviour of charm quarks by the LHCb collaboration – is too small to account for the cosmological matter–antimatter imbalance. Searching for new sources of CP violation is thus of great interest to physicists.
管,粒子物理的模型,能解反荷奇偶性。不,迄今在中,被到的反荷奇偶性量太少,法明宇宙之物反物的不平衡。因此,物理家非常感趣於,搜反荷奇偶性的新源。
In their recent studies, the CMS and ATLAS teams independently performed a direct test of the properties of the top–Higgs interaction. The studies are based on the full dataset of Run 2 of the LHC, which allowed for more precise measurements and analyses of the collision events where the Higgs boson is produced in association with one or two top quarks before decaying into two photons.
在最近的研究中,CMS及ATLAS的立行了,有夸克希格斯玻色子交互作用的性直接。此些研究是根,大型子撞第二次作的完整集。使人得以更精定及分析,在衰成光子之前,希格斯玻色子被生之1或2夸克的撞事件。
The detection of this extremely rare association, which was first observed by the two collaborations in 2018, required the full capacities of the detectors and analysis techniques.
於2018年,由上述共同研究,行首度之其罕的合,需要完整的探器及分析技能耐。
As predicted by the Standard Model, no signs of CP violation were found in the top–Higgs interaction by either experiment. The top–Higgs production rate, a measure of the strength of the interaction between the particles, was also found by both experiments to be in line with previous results and consistent with the Standard Model predictions.
如同模型所,在由上述任一之夸克希格斯玻色子的交互作用中,皆未反荷奇偶性的象。不,夸克希格斯玻色子的生率(粒子之交互作用度的一定),先前的研究果相符合,且模型的一致。
Following these first investigations of CP violation in the top–Higgs interaction, ATLAS and CMS physicists plan to study other Higgs-boson decay channels as part of the decades-long search for the origin of the universe’s missing antimatter.
些在夸克希格斯玻色子交互作用中,反荷奇偶性的首度查研究之後,ATLAS及CMS的物理家,研究其他希格斯玻色子的衰途,作十年找,宇宙行不明之反物起因的一部分。
