تجربة أطلس حول المعجل النووي العملاق النووي هادرون (A Toroidal LHC ApparatuS, Aparato Toroidal ل LHC)) هومكشاف جزيئات صمم مع خمسة تجارب أخرى (ALICE, CMS,TOTEM وLHCb) في مصادم الهدرونات الكبير.
التجربة الفيزيائية تمت ما بين الحدود الفرنسية السويسرية يوم الأربعاء 17 سبتمبر 2008. ويعتبر هذا المشروع، الذي كلف 3.76 مليار يورو، ثمرة تعاون بين البلدان الأوروبية والولايات المتحدة والهند وروسيا واليابان. ويعد المغرب البلد العربي والأفريقي الوحيد الذي شارك في هذه التجربة كما أنه ساهم في بناء مولد المجال المغناطيسي أحد مكونات الهادرون.

الخلفية
ATLAS experiment detector under construction in October 2004 in its experimental pit; the current status of construction can be seen here. Note the people in the background, for comparison.
برنامج الفيزياء
A schematic, called a Feynman diagram, of two virtual gluons from colliding LHC protons interacting to produce a hypothetical Higgs boson, a top quark, and an antitop quark. These in turn decay into a specific combination of quarks and leptons that is very unlikely to be duplicated by other processes. Collecting sufficient evidence of signals like this one may eventually allow ATLAS collaboration members to discover the Higgs boson.
