“大”除数D3/D7瑞士奶酪现象学

"Big" Divisor D3/D7 Swiss Cheese Phenomenology

Aalok Misra

摘要:

我们回顾了过去几年在瑞士奶酪现象学领域所取得的进展,涉及一个流动的时空填充D3-膜和一堆(S)的通量D 7-膜包装的“大”(而不是“小”)除数(orientifold的)瑞士奶酪Calabi-Yau。综述的主题包括大体积宇宙学和唯象学的调和,软超对称破缺参数的评估,标量质量的单圈RG流方程的解,获得O(MeV-GeV)区的费米子(可能是前两代夸克/轻子)质量标度以及(前两代)eV左右的中微子质量(及其单圈RG流)。重的超对称粒子和轻的费米子预示了“分裂超对称”大体积的可能性。

英文摘要:

We review progress made over the past couple of years in the field of Swiss Cheese Phenomenology involving a mobile space-time filling D3-brane and stack(s) of fluxed D7-branes wrapping the "big" (as opposed to the "small") divisor in (the orientifold of a) Swiss-Cheese Calabi-Yau. The topics reviewed include reconciliation of large volume cosmology and phenomenology, evaluation of soft supersymmetry breaking parameters, one-loop RG-flow equations' solutions for scalar masses, obtaining fermionic (possibly first two generations' quarks/leptons) mass scales in the O(MeV-GeV)-regime as well as (first two generations') neutrino masses (and their one-loop RG flow) of around an eV. The heavy sparticles and the light fermions indicate the possibility of "split SUSY" large volume scenario.
