Using recent developments of establishing an exact lattice chiral symmetry, a chirally invariant Yukawa-model will be investigated using lattice methods. As a first step, the quenched phase diagram of the model and properties of the emerging phases will be studied. In a second step, the realistic dynamical case will be investigated. Besides the exploration of the phase diagram in this case, phenomenologically relevant quantities such as the Higgs boson and top quark masses and the strength of the Yukawa and Higgs couplings will be computed. In the long run, also the decay width of the Higgs boson will be addressed.

利用最近的发展，建立一个确切的晶格手征对称性，手征不变的Yukawa模型将使用晶格方法进行研究。作为第一步，淬火相图的模型和新兴相的属性将进行研究。在第二步中，将研究现实的动力学情况。除了在这种情况下的相图的探索，希格斯玻色子和顶夸克质量和汤川和希格斯耦合的强度等唯象相关的量将被计算。从长远来看，希格斯玻色子的衰变宽度也将得到解决。
