L'existence de grandes dimensions supplémentaires peut être sondée dans diverses expériences sur les neutrinos. Nous analysons plusieurs ensembles de données sur les neutrinos dans un modèle avec une grande dimension supplémentaire dominante. Nous montrons que l'anomalie du gallium peut être expliquée par des oscillations de neutrinos induites par la grande dimension supplémentaire, mais la région de l'espace des paramètres qui est préférée par l'anomalie du gallium est en tension avec les limites des données de vitesse du réacteur, ainsi que les données de Daya Bay et MINOS. Nous présentons également les bornes obtenues à partir de l'analyse des données KATRIN. Nous montrons que les expériences actuelles peuvent mettre des bornes fortes sur la taille ${R}_{\mathrm{ED}}$ de la dimension supplémentaire : ${R}_{\mathrm{ED}}<0,20\text{ }\text{ }\ ensuremath {\mu}\mathrm{m}$ et ${R}_{\mathrm{ED}}<0,10\text{ }\text{ }\ ensuremath {\mu}\mathrm{m}$ à 90% C.L. pour l'ordre normal et inversé des masses de neutrinos standard, respectivement.
La existencia de grandes dimensiones adicionales se puede probar en varios experimentos con neutrinos. Analizamos varios conjuntos de datos de neutrinos en un modelo con una gran dimensión extra dominante. Mostramos que la anomalía del galio se puede explicar con oscilaciones de neutrinos inducidas por la gran dimensión adicional, pero la región del espacio de parámetros preferida por la anomalía del galio está en tensión con los límites de los datos de velocidad del reactor, así como los datos de Daya Bay y MINOS. También presentamos los límites obtenidos del análisis de los datos de KATRIN. Demostramos que los experimentos actuales pueden poner límites fuertes en el tamaño ${R}_{\mathrm{ED}}$ de la dimensión adicional: ${R}_{\mathrm{ED}}<0.20\text{ }\text{ }\ ensuremath {\mu}\mathrm{m}$ y ${R}_{\mathrm{ED}}<0.10\text{ }\text{ }\ ensuremath {\ mu}\mathrm{m}$ al 90% C.L. para el ordenamiento normal e invertido de las masas de neutrinos estándar, respectivamente.
The existence of large extra dimensions can be probed in various neutrino experiments. We analyze several neutrino datasets in a model with a dominant large extra dimension. We show that the gallium anomaly can be explained with neutrino oscillations induced by the large extra dimension, but the region of parameter space that is preferred by the gallium anomaly is in tension with the bounds from reactor rate data, as well as the data of Daya Bay and MINOS. We also present bounds obtained from the analysis of the KATRIN data. We show that current experiments can put strong bounds on the size ${R}_{\mathrm{ED}}$ of the extra dimension: ${R}_{\mathrm{ED}}<0.20\text{ }\text{ }\ ensuremath {\mu}\mathrm{m}$ and ${R}_{\mathrm{ED}}<0.10\text{ }\text{ }\ ensuremath {\mu}\mathrm{m}$ at 90% C.L. for normal and inverted ordering of the standard neutrino masses, respectively.

يمكن التحقق من وجود أبعاد إضافية كبيرة في تجارب النيوترينو المختلفة. نقوم بتحليل العديد من مجموعات بيانات النيوترينو في نموذج ذي بعد إضافي كبير مهيمن. نظهر أنه يمكن تفسير شذوذ الغاليوم بتذبذبات النيوترينو الناجمة عن البعد الإضافي الكبير، ولكن منطقة مساحة المعلمة التي يفضلها شذوذ الغاليوم متوترة مع الحدود من بيانات معدل المفاعل، وكذلك بيانات خليج دايا ومينوس. نقدم أيضًا الحدود التي تم الحصول عليها من تحليل بيانات KATRIN. نوضح أن التجارب الحالية يمكن أن تضع حدودًا قوية على الحجم ${R}_{\ mathrm{ED}}$ للبعد الإضافي: ${R}_{\ mathrm{ED}}<0.20\text{}\text {}\ ensuremath {\ mu}\ mathrm{m }$ و ${R}_{\ mathrm{ED}}<0.10\text{}\text {}\ ensuremath {\ mu}\ mathrm{m }$ عند 90 ٪ CL للترتيب العادي والمقلوب لكتل النيوترينو القياسية، على التوالي.
