Search for dark matter candidates and large extra dimensions in events with a jet and missing transverse momentum with the ATLAS detector
A bstract Se realiza una búsqueda de nuevos fenómenos en eventos con un chorro de alta energía y gran momento transversal faltante utilizando datos de colisiones protón-protón a $ \sqrt{s}=7 $ TeV con el experimento ATLAS en el Gran Colisionador de Hadrones. Se exploran cuatro regiones cinemáticas utilizando un conjunto de datos correspondiente a una luminosidad integrada de 4.7 fb −1 . No se observa un exceso de eventos más allá de las expectativas de los procesos del Modelo Estándar, y se establecen límites en las grandes dimensiones adicionales y la producción de pares de partículas de materia oscura.
A bstract A search for new phenomena in events with a high energy jet and large missing transverse momentum is performed using data from proton-proton collisions at $ \sqrt{s}=7 $ TeV with the ATLAS experiment at the Large Hadron Collider. Quatre régions cinématiques sont explorées à l'aide d'un ensemble de données correspondant à une luminosité intégrée de 4,7 fb −1 . Aucun excès d'événements au-delà des attentes des processus du modèle standard n'est observé, et des limites sont fixées pour les grandes dimensions supplémentaires et la production de paires de particules de matière noire.

Four kinematic regions are explored using a dataset corresponding to an integrated luminosity of 4.7 fb −1 . No excess of events beyond expectations from Standard Model processes is observed, and limits are set on large extra dimensions and the pair production of dark matter particles.
ملخص يتم إجراء البحث عن ظواهر جديدة في الأحداث ذات النفاثة عالية الطاقة والزخم العرضي الكبير المفقود باستخدام بيانات من تصادمات البروتون والبروتون عند $\sqrt{s}=7 $ TeV مع تجربة أطلس في مصادم الهدرونات الكبير. يتم استكشاف أربع مناطق حركية باستخدام مجموعة بيانات تتوافق مع لمعان متكامل قدره 4.7 fb −1 . لم يتم ملاحظة أي زيادة في الأحداث تتجاوز التوقعات من عمليات النموذج القياسي، ويتم تعيين الحدود على أبعاد إضافية كبيرة وإنتاج زوج من جزيئات المادة المظلمة.
