The decays of the Higgs boson H_1→Z_γ are discussed in the simplest 3-3-1 model. Analytic formulas for one-loop contributions were constructed using well-known general results. We will show that new particles predicted by this simplest 3-3-1 model may gice significant effects to this decay of the standard model-like Higgs boson. From numerical investigation, some details and properties of this decay are presented. the may be useful for comparing with the experimental results that will be detected in the future.

Progress made on the theoretical aspects of the standard model contributions to the anomalous magnetic moment of the charged leptons since the first FCCP Workshop on Capri in 2015 is reviewed. Emphasis is in particular given to the various cross-checks that have already become available, or might become available in the future, for several important contributions.

Besides the traditional strong and electromagnetic decay modes,Υ(nS)meson can also decay through the weak interactions within the standard model of elementary particle. With anticipation of copiousΥ(nS)data samples at the running LHC and coming SuperKEKB experiments, the two-body nonleptonic bottom-changingΥ(nS)→Bc⁎π,Bc⁎Kdecays (n=1,2,3) are investigated with perturbative QCD approach firstly. The absolute branching ratios forΥ(nS)→Bc⁎πandBc⁎Kdecays are estimated to reach up to about10-10and10-11, respectively, which might possibly be measured by the future experiments.

Despite the undeniable success of the Standard Model of particle physics (SM), there are some phenomena (neutrino oscillations, baryon asymmetry of the Universe, dark matter, etc.) that SM cannot explain. This phenomena indicate that the SM have to be modified. Most likely, there are new particles beyond the SM. There are many experiments to search for new physics that can be can divided into two types: energy and intensity frontiers. In experiments of the first type, one tries to directly produce and detect new heavy particles. In experiments of the second type, one tries to directly produce and detect new light particles that feebly interact with SM particles. The future intensity frontier SHiP experiment (Search for Hidden Particles) at the CERN SPS is discussed. Its advantages and technical characteristics are given.
