. Dans-l-'étude-actuelle, estimation du bruit de fond réductible ainsi que la détermination de la composition du bruit de fond sont déjà catégorisées. Le calcul d'un facteur correctif Diphox/Pythia catégorisé permettrait d'obtenir une estimation complète du bruit de fond par catégorie et ainsi de mener à bien une comparaison des données avec l'estimation du bruit de fond simultanément en

. Tev, Cette expérience de comptage a permis de contraindre, avec 95 % de niveau de confiance, la présence d'un nouveau phénomène prévoyant plus de 7.2 événements avec une masse invariante diphoton supérieure à 1217 GeV Cette contrainte a ensuite été traduite en une limite sur l'échelle de coupure ultraviolette M S dans le contexte du modèle ADD. En connaissant l'efficacité de détection d'un photon (c.f. appendice B), il est toutefois possible d'interpréter la contrainte sur le nombre d'événements en une contrainte sur un autre modèle prévoyant des manifestations dans des événements diphoton aux propriétés cinématiques proches de celles du modèle ADD, traitement statistique plus élaboré , tirant profit des différences entre le bruit de fond et le signal ADD dans les distributions de Bibliographie
