具有dim-5相互作用的大统一理论:规范统一和中间尺度

GUTs with dim-5 interactions: Gauge Unification and Intermediate Scales

Joydeep Chakrabortty, Amitava Raychaudhuri

摘要:

对大统一理论(GUTs)规范动力学项的五维修正可能会捕获量子引力或弦紧化的影响。这种算子以可计算的方式修正了通常的规范耦合统一预测。在这里,我们检查SU(5),SO(10),和E(6)大统一理论在所有这些允许的运营商的光,并计算对中间尺度和统一计划的影响。我们表明,在许多情况下,至少有一个中间尺度可以降低到甚至1-10 TeV,其中中性Z'和可能的其他国家的预期。

英文摘要:

Dimension-5 corrections to the gauge kinetic term of Grand Unified Theories (GUTs) may capture effects of quantum gravity or string compactification. Such operators modify the usual gauge coupling unification prediction in a calculable manner. Here we examine SU(5), SO(10), and E(6) GUTs in the light of all such permitted operators and calculate the impact on the intermediate scales and the unification programme. We show that in many cases at least one intermediate scale can be lowered to even 1-10 TeV, where a neutral Z' and possibly other states are expected.
