ILC上的两个普适额外维和无自旋光子

Two universal extra dimensions and spinless photons at the ILC

Ayres Freitas, Kyoungchul Kong

摘要:

我们研究了在手征正方形上紧化的两个普适额外维上的(1,0)Kaluza-Klein(KK)模的ILC现象。我们计算了sqrt(s)=1 TeV的ILC中各种(1,0)粒子的产生截面,重点是KK轻子和超荷规范玻色子的KK伙伴衰变到“无自旋光子”,这是最轻的KK粒子。我们将这个模型与具有KK光子(自旋1)的一个普遍额外维度和具有中性伴子(自旋1/2)或引力伴子(自旋3/2)暗物质的超对称性进行了对比。我们还研究了(1,1)KK玻色子作为s-通道共振的发现潜力。

英文摘要:

We study the ILC phenomenology of (1,0) Kaluza-Klein (KK) modes along two universal extra dimensions compactified on the chiral square. We compute production cross sections of various (1,0) particles at the ILC with sqrt(s)=1 TeV, focusing on decays of KK-leptons and the KK partner of hypercharge gauge boson down to the "spinless photon", which is the lightest KK particle. We contrast this model to one universal extra dimension with KK-photon (spin-1) and supersymmetry with neutralino (spin-1/2) or gravitino (spin-3/2) dark matter. We also investigate the discovery potential for (1,1) KK bosons as s-channel resonances.
