Asymmetric dark matter, inflation, and leptogenesis from B−L symmetry breaking

Abstract

Nous proposons une configuration unifiée pour la génération de la matière noire, de l'inflation et de l'asymétrie baryonique par le mécanisme de bascule de la masse des neutrinos. Notre scénario émerge naturellement d'un groupe de jauges étendues contenant $B\text{\ensuremath{-}}L$ comme une symétrie non commutative, brisée par un scalaire singulet qui entraîne également l'inflation. Ses désintégrations réchauffent l'univers, produisant le neutrino droitier le plus léger. La conservation automatique de la parité matière conduit à la stabilité d'un candidat matière noire asymétrique, directement liée à l'asymétrie matière-antimatière dans l'Univers.

Proponemos una configuración unificada para la materia oscura, la inflación y la generación de asimetría bariónica a través del mecanismo de balancín de masa de neutrinos. Nuestro escenario surge naturalmente de un grupo de gauge extendido que contiene $B\text{\ensuremath{-}}L$ como una simetría no conmutativa, rota por un escalar singlete que también impulsa la inflación. Sus desintegraciones recalientan el universo, produciendo el neutrino diestro más ligero. La paridad automática de la materia conduce a la estabilidad de un candidato asimétrico a materia oscura, directamente relacionado con la asimetría materia-antimateria en el Universo.

We propose a unified setup for dark matter, inflation, and baryon asymmetry generation through the neutrino mass seesaw mechanism. Our scenario emerges naturally from an extended gauge group containing $B\text{\ensuremath{-}}L$ as a noncommutative symmetry, broken by a singlet scalar that also drives inflation. Its decays reheat the universe, producing the lightest right-handed neutrino. Automatic matter parity conservation leads to the stability of an asymmetric dark matter candidate, directly linked to the matter-antimatter asymmetry in the Universe.

نقترح إعدادًا موحدًا للمادة المظلمة والتضخم وتوليد عدم تناسق الباريونات من خلال آلية تأرجح كتلة النيوترينو. يظهر سيناريو لدينا بشكل طبيعي من مجموعة قياس موسعة تحتوي على $B\text{\ ensuremath {-}}L$ كتناظر غير تبادلي، مكسور بواسطة مقياس فردي يدفع أيضًا التضخم. تعيد اضمحلاله تسخين الكون، مما ينتج أخف نيوترينو باليد اليمنى. يؤدي الحفظ التلقائي لتكافؤ المادة إلى استقرار مرشح المادة المظلمة غير المتماثل، المرتبط مباشرة بعدم تناظر المادة والمادة المضادة في الكون.
