We formulate a generalization of Higgs effective field theory (HEFT) including arbitrary number of extra neutral and charged Higgs bosons (generalized HEFT, GHEFT). Using the geometrical form of the GHEFT Lagrangian, which can be regarded as a nonlinear sigma model on a scalar manifold, it is shown that the scalar boson scattering amplitudes at high energy are described in terms of the Riemann...

We examine the discovery potential for double Higgs production at the HL-LHC in the bbWW dilepton channel. Although dilepton channel suffers from the large backgrounds, we propose that it is possible to get signal significance improvement by adopting a deep learning frame work making full use of the relevant kinematics. The method can be generalized to other processes with similar final states.

There are several flavor anomalies in RD^(*), muon g-2 and so on. It is known that a general two Higgs doublet model can improve those deviations. I will discuss the collider bounds for the scenario. This talk is based on our works: 1810.05843 and the work in progress with Yuji Omura and Michihisa Takeuchi.

Two Higgs doublet model (2HDM), in which one more Higgs doublet is added to the Standard Model(SM), is one of the most simple extensions of the SM. We show that there is a stable magnetic monopole solution in a certain parameter range of 2HDM. In particular, the stability of the monopole is topologically ensured when the Higgs potential has a U(1) symmetry and a discrete $\mathbb{Z}_2$...

We introduce a new neural network architecture (Complex-valued Neural Arithmetic Logic Units, CALU), for learning and extraction of physical features. We also demonstrate and discuss on its potential implications on building more physical machine learning models for science including HEP.

There are many models beyond the standard model which include electroweakly interacting massive particles (EWIMPs), often in the context of the dark matter. We study the indirect search of EWIMPs using a precise measurement of the lepton pair production cross sections at future 100 TeV hadron colliders. It is revealed that this search strategy is suitable in particular for Higgsino and that...

Motivated by the long-lasting 3.5σ discrepancy in the anomalous magnetic moment of muon, we consider a new muon-specific force mediated by a light gauge boson, X, with mass mX<2mμ and the coupling constant gX∼(10−4,10−3). We show that the Belle II experiment has a robust chance to probe such a light boson in e+e−→μ+μ−+X channel and cover the most interesting parameter space explaining the...

The charged lepton flavor violation (CLFV) is a good probe to search for new physics beyond the standard model. If there is a neutral boson X which is lighter than muon and has CLFV interaction, a muon can decay into an electron and an X, i.e. mu->e+X. The search for this process is expected to constraint the property of X. In this talk, we focus on a search for the decay in muonic atom due to...

The string swampland conjectures are giving severe constraint on the cosmological models. How we can respect the swampland conjectures and still can have viable cosmological models will be discussed in this talk.
