[3]. In this setup, there are 3 + n spatial dimensions, with n compact dimensions of a typical compactification radius R. All matter and gauge fields are confined to a four-dimensional slice, a brane. Web7 de dez. de 2024 · Fred Jegerlehner We argue that the Standard Model (SM) in the Higgs phase does not suffer from a "hierarchy problem" and that similarly the "cosmological constant problem" resolves itself if we understand the SM as a low energy effective theory emerging from a cutoff-medium at the Planck scale. extra space storage boston
