We set the cosmological constant \Lambda is not canstant but a function of Hubble parameter, and \Lambda can decay with matter and radiation in the expansion universe. We examine the running vacuum model with \Lambda(H) = 3\nuH^2 + \Lambda_0, where \nu is the model parameter and \Lambda_0 is the cosmological constant. From the data of the cosmic microwave background radiation, weak lensing and bar

We investigate decay modes of spin-1 heavy vector bosons (V') from the viewpoint of perturbative unitarity in a model-independent manner. Our findings are: [1] Br(W'->WZ) is less than 2% in the system that contains V' and CP-even scalars as well as the SM particles. [2] Contributions of CP-odd scalars help to make Br(W'->WZ) larger than Br(W'->ff) as long as the CP-odd scalars couple to both the S

In this presentation we consider doubly charged scalars pair
production and decays within the Higgs Triplet Model (HTM) in
lepton and hadron colliders. The HTM is an extension of the Standard
Model realising the type II seesaw mechanism [1]. The additional scalar
triplet contains the doubly charged particle H++, which contributes to
lepton flavour violating (LFV) processes. We discu

In the standard model, the negative mass parameter is introduced in the Higgs potential to occur electroweak symmetry breaking. In a class of models based on classically scale invariance, parameters with mass dimensions in the Lagrangian are prohibited by classically scale invariance and electroweak symmetry breaking dynamically occurs by Coleman and Weinberg mechanism.
In this talk, I focus on

Dynamical relaxation provides an interesting solution to the hierarchy problem, which allows to produce a large hierarchy of scales without abandoning the naturalness principle. The observed value of the electroweak scale is then a consequence of an interaction between the Higgs boson and a new axion-like field, a relaxion. Attempts at extending this mechanism to a two-doublet scenario (arXiv:1612

We consider three different series of problems
1. The t–channel singularity in small angle scattering (almost solved).
In the processes like \mu^+\mu^-\to W e\nu with effective mass e\nu lower than m_\mu transferred momentum of \nu can be both space-like and time-like. In the naive approach it gives divergent cross section. This difficulty is eliminated when treat initial states as wave pack
