Joseph P. Conlon, Lukas T. Witkowski

摘要:

我们研究的散射和隔离的爆破领域-无论是本地或远离可见物质部门-通过CFT计算的依赖性的物理汤川耦合的爆破模量。对于轨道奇点上的D3-膜的一个可见扇区,我们计算圆盘相关器< τ_s^{(1)} τ_s^{(2)}.τ_s^{(n)} τ_s ^{(n)} τ_s ^{(n)}对于n = 1,我们确定完整的量子和经典相关器。这个结果在低3点函数上具有正确的因式分解,并且还通过了许多其他一致性检查。当n > 1时,我们证明了应用于扭曲算子的图像变换结构建立了在圆盘水平上的远距离爆破模对所有阶的隔离。我们解释了这些结果是如何相关的抑制软条款的尺度参数低于引力子质量。通过给爆破场赋予vevs,我们可以进入光滑极限,从而推导出出现在大体积场景中的光滑瑞士奶酪Calabi-Yaus的CFT结果。

英文摘要:

We study the scattering and sequestering of blow-up fields - either local to or distant from a visible matter sector - through a CFT computation of the dependence of physical Yukawa couplings on the blow-up moduli. For a visible sector of D3-branes on orbifold singularities we compute the disk correlator < τ_s^{(1)} τ_s^{(2)} ... τ_s^{(n)} ψψϕ> between orbifold blow-up moduli and matter Yukawa couplings. For n = 1 we determine the full quantum and classical correlator. This result has the correct factorisation onto lower 3-point functions and also passes numerous other consistency checks. For n > 1 we show that the structure of picture-changing applied to the twist operators establishes the sequestering of distant blow-up moduli at disk level to all orders in α'. We explain how these results are relevant to suppressing soft terms to scales parametrically below the gravitino mass. By giving vevs to the blow-up fields we can move into the smooth limit and thereby derive CFT results for the smooth Swiss-cheese Calabi-Yaus that appear in the Large Volume Scenario.
