疏轻子Z'玻色子的精密探测

Precision Probes of a Leptophobic Z' Boson

Matthew R. Buckley, Michael J. Ramsey-Musolf

摘要:

包含疏轻子Z'规范玻色子的标准模型的扩展在理论上是有趣的,但难以在高能强子对撞机中直接探测。然而,标准模型中性电流过程的精确测量可以提供强大的间接测试。我们证明,宇称违反深度非弹性散射的极化电子离开氘提供了一个独特的探针疏轻子Z'玻色子与轴向夸克耦合和质量超过100 GeV。除了覆盖广泛的以前未知的参数空间,计划测量的深度非弹性宇称违反eD不对称性将能够测试疏轻子Z'的情况下提出的解释CDF W加双喷异常。

英文摘要:

Extensions of the Standard Model that contain leptophobic Z' gauge bosons are theoretically interesting but difficult to probe directly in high-energy hadron colliders. However, precision measurements of Standard Model neutral current processes can provide powerful indirect tests. We demonstrate that parity-violating deep inelastic scattering of polarized electrons off of deuterium offer a unique probe leptophobic Z' bosons with axial quark couplings and masses above 100 GeV. In addition to covering a wide range of previously uncharted parameter space, planned measurements of the deep inelastic parity-violating eD asymmetry would be capable of testing leptophobic Z' scenarios proposed to explain the CDF W plus di-jet anomaly.
