Taomeow Posted February 3, 2017 Applying the Ashok-Denef-Douglas estimation method to elliptic Calabi-Yau fourfolds suggests that a single elliptic fourfold Mmax gives rise to O(10272,000) F-theory flux vacua, and that the sum total of the numbers of flux vacua from all other F-theory geometries is suppressed by a relative factor of O(10−3000). The fourfold Mmax arises from a generic elliptic fibration over a specific toric threefold base Bmax, and gives a geometrically non-Higgsable gauge group of E98×F84×(G2×SU(2))16, of which we expect some factors to be broken by G-flux to smaller groups. It is not possible to tune an SU(5) GUT group on any further divisors in Mmax, or even an SU(2) or SU(3), so the standard model gauge group appears to arise in this context only from a broken E8 factor.  I simplified as much as I could.   4 Share this post Link to post Share on other sites

Taomeow Posted February 3, 2017 You didn't get anywhere close to my needs.   Sorry... the multiverse isn't easy to simplify. Working on it. 2 Share this post Link to post Share on other sites
