标题： Pole-Induced Higgs Inflation With Hyperbolic Kaehler Geometries

摘要： 我们提出了超引力框架下希格斯暴胀的全新实现方式，这些实现方式主要与膨胀子场动能项中的二阶极点的存在密切相关。 这个极点出现是由于所选择的Kähler势，它们参数化了(SU(1,1)/U(1))^2 或 SU(2,1)/(SU(2)xU(1)) 流形，其标量曲率分别为 R_{(11)^2}=-4/N 或 R_{21}=-3/N。 相关的超势除了包含希格斯超场外，还包括一个稳定器超场，满足规范对称性和R对称性，并包含第一个允许的不可重正化项。 如果该不可重正化项的系数与可重正化项的系数在约10^-5的范围内几乎相等且N=1时，暴胀观测值可以与当前数据兼容，规范对称破缺尺度M可能假设其在MSSM中的值。 然而，增加M超过这个值，暴胀可以通过较少的调整实现。 对上述流形相关的Kähler势的修改允许仅通过可重正化项实现暴胀，随着N接近其最大值N=40，张量到标量比值会更高。 显示英文摘要

摘要： We present novel realizations of Higgs inflation within Supergravity which are largely tied to the existence of a pole of order two in the kinetic term of the inflaton field. This pole arises due to the selected Kaehler potentials which parameterize the (SU(1,1)/U(1))^2 or SU(2,1)/(SU(2)xU(1)) manifolds with scalar curvatures R_{(11)^2}=-4/N or R_{21}=-3/N respectively. The associated superpotential includes, in addition to the Higgs superfields, a stabilizer superfield, respects the gauge and an R symmetries and contains the first allowed nonrenormalizable term. If the coefficient of this term is almost equal to that of the renormalizable terms within about 10^-5 and N=1, the inflationary observables can be done compatible with the present data and the scale M of gauge-symmetry breaking may assume its value within MSSM. Increasing M beyond this value, though, inflation may be attained with less tuning. Modifications to the Kaehler potentials associated with the manifolds above allow for inflation, realized with just renormalizable terms, resulting to higher tensor-to-scalar ratios as N approaches its maximum at N=40.
