The expected tensor-to-scalar ratio estimate of the upcoming CMB mission probe measurements may establish a lower value of the ratio than the currently obtained value. It can be described in terms of a single field chaotic inflation model along with the curvaton or quantum gravity or their combined effect. Consequently, the role of quantum gravity or curvaton in the dynamics of the early universe may not be ruled out. The curvaton scenario and quantum gravity effect can be tested experimentally. The upcoming CMB missions can validate the curvaton scenario and quantum gravity experimentally.

曲率和量子引力对混沌暴胀张量标量比的影响

即将到来的 CMB 任务探测测量的预期张量-标量比估计可以建立比当前获得的值更低的比值。它可以用单场混沌膨胀模型以及曲率或量子引力或其组合效应来描述。因此，不能排除量子引力或曲率在早期宇宙动力学中的作用。可以通过实验测试曲率情景和量子引力效应。即将到来的 CMB 任务可以通过实验验证曲率情景和量子引力。
