Tóm tắt

Chúng tôi xây dựng các lý thuyết Đại thống nhất SU(5) dạng gọn trong lý thuyết F, trong đó sự phá vỡ GUT được thực hiện qua một đường Wilson rời rạc. Do trường gauge nội tại là phẳng, các mô hình này tránh được các điều chỉnh ngưỡng ở quy mô cao liên quan đến dòng hypercharge. Trong quá trình này, chúng tôi minh họa cách tiếp cận 'từ địa phương đến toàn cầu' trong việc xây dựng mô hình lý thuyết F và chứng minh cách mà hình thức chia Tate có thể được sử dụng để giải quyết một số thách thức trong việc mở rộng các mô hình địa phương thành các mô hình toàn cầu. Điều này đặc biệt bao gồm việc xây dựng các G-flux mở rộng các bó không thừa kế và thiết kế các đối xứng U(1). Chúng tôi vượt ra ngoài tính toán chirality và xác định phổ chính xác của các hạt (không mang điện) mà tìm thấy chính xác ba gia đình quark và lepton, nhưng lại có nhiều cặp doublet và/hoặc triplet dư thừa trong lĩnh vực Higgs (tùy thuộc vào ví dụ) và các hạt ngoại lai kiểu vector phát sinh từ phần phụ của SU(5)GUT. Hiểu lý do tại sao các cặp kiểu vector vẫn tồn tại trong lĩnh vực Higgs mà không có một đối xứng rõ ràng để bảo vệ chúng có thể giúp tìm ra các giải pháp mới cho vấn đề μ trong các GUT của lý thuyết F.
