The discovery of a Higgs boson at LHC could indicate that there is more than one.Our most popular theory for Dark Matter, supersymmetry, predicts the existenceof 5 Higgs bosons, and searching for another is now a very high priority. This is particularly timely in 2015 as the restart of the LHC at (or close to) is design energy means that heavy objects will be produced much more easily than before. There is thereforean excellent opportunity to look for new heavier Higgs bosons. In supersymmetry the most likely decay mode of such a particle is into pairs of 'tau' leptons. Warwick has alot of expertise in the study of the first Higgs boson to these particles, and it is natural totry to extend our studies to a possible heavier particle. The increased LHC beam energy might produce other heavy particles. For example aWarwick student is preparing to search for a new heavy boson (W') resembling the W boson of the weak nuclear force. His studies include this boson decaying into an ordinary W bosonand a Z. This grant should allow us to extend that search to also cover decay to a W and aHiggs, with both of these decaying into 'jets'. This is not currently studied in ATLAS butshould be the most sensitive mode for a high-mass W' Whether either of these possibilities really occurr we do not know - but we canonly find out by looking.

在大型强子对撞机上发现希格斯玻色子可能表明存在不止一个希格斯玻色子。我们最流行的暗物质理论超对称性预测了5个希格斯玻色子的存在，寻找另一个希格斯玻色子现在是非常重要的优先事项。这在2015年尤为及时，因为大型强子对撞机在设计能量下(或接近设计能量)重新启动意味着，重物的产生将比以前容易得多。因此，这是寻找新的更重的希格斯玻色子的绝佳机会。在超对称性中，这种粒子最有可能的衰变模式是成对的“tau”轻子。沃里克在研究这些粒子的第一个希格斯玻色子方面有很多专业知识，自然会尝试将我们的研究扩展到可能更重的粒子。大型强子对撞机束流能量的增加可能会产生其他重粒子。例如，华威大学的一名学生正准备寻找一种新的重玻色子(W‘)，类似于弱核力的W玻色子。他的研究包括这个玻色子衰变成一个普通的W玻色子和一个Z玻色子。这笔拨款应该允许我们将研究范围扩大到衰变到W玻色子和a希格斯玻色子，这两个玻色子都衰变成“喷流”。这目前还没有在ATLAS中进行研究，但对于大质量的W‘来说，这应该是最敏感的模式，我们不知道这两种可能性是否真的会发生--但我们只能通过观察来找出答案。
