大型强子对撞机上的六轻子Z'共振

Six-Lepton Z' Resonance at the Large Hadron Collider

Vernon Barger, Paul Langacker, Hye-Sung Lee

摘要:

新的物理模型承认了一种有趣的可能性,即Z'弱玻色子与额外的U(1)规范对称性和希格斯玻色子相关联,希格斯玻色子的重量足以衰变为一对Z玻色子。然后通过Z' -> ZH -> ZZZ的Z'产生和衰变具有独特的LHC信号,该信号几乎没有背景,并且重建了H和Z'的质量和宽度。Z'衰变到3对轻子的过程特别独特。即使Z'与轻子解耦,ZH衰变模式也存在,这激发了独立的6轻子共振搜索,而不管双轻子搜索结果如何。

英文摘要:

New physics models admit the interesting possibility of a Z' weak boson associated with an extra U(1) gauge symmetry and a Higgs boson that is heavy enough to decay into a pair of Z bosons. Then Z' production and decay via Z' -> ZH -> ZZZ has a distinctive LHC signal that is nearly background free and reconstructs the H and Z' masses and widths. The Z' decay to 3 pairs of leptons is especially distinctive. The ZH decay mode exists even if the Z' is decoupled from leptons, which motivates an independent 6-lepton resonance search regardless of the dilepton search results.
