1. Muon g-2 and/or B anomaliles in some gauge extensions of the SM

Prof. Pyungwon Ko (KIAS)

21/05/2021, 15:40

Theory

In this talk, I will discuss a few gauge extensions of the SM where one can accommodate the muon g-2 and/or B anomalies.

2. Neutrino mass and muon g-2 with dark U(1) symmetry

Prof. Myeonghun Park (University of Seoul, Department of Physics (KR))

21/05/2021, 16:00

Theory

We propose an extension of the Standard Model (SM) for radiative neutrino mass by introducing a dark U(1) gauge symmetry. We show that the tiny neutrino mass and dark matter candidates are naturally accommodated. Motivated by the recent measurement of muon (g−2) indicating 4.2  deviation from the SM prediction, we examine how this deviation  can be explained in this model.

3. Leptophilic pseudoscalar and muon g-2 in 2HDM

Prof. Eung Jin Chun (Korea Institute for Advanced Study)

21/05/2021, 16:20

Theory

The type-X 2HDM is known to explain the long-standing muon g-2 anomaly due to the presence of a light CP-odd Higgs boson which becomes leptophilic at large tanbeta. The model can be extended with an even lighter singlet boson contributing to the muon g-2. We discuss the current experimental limits on the model and the discovery potential of the extra (Higgs) bosons at lepton and proton colliders.

4. Type-X two Higgs doublet model in light of muon g-2: confronting the Higgs and collider data

Prof. Jeonghyeon Song (Konkuk University)

21/05/2021, 16:40

Theory

The recent Fermilab measurement of the muon anomalous magnetic moment yields about 4.2 sigma deviation from the SM prediction. In the Type-X two Higgs doublet model with the Higgs alignment, we study the consequence of imposing the observed muon g-2, along with the theoretical stabilities, electroweak oblique parameters, Higgs precision data, and direct searches at the LEP and LHC. We found...

5. Leptoquark option for B-meson anomalies and leptonic signatures

Prof. Hyun Min Lee (CAU - Chung-Ang University (KR))

21/05/2021, 17:00

Theory

We entertain the option of scalar leptoquarks to explain the anomalies in the semi-leptonic decays of B-mesons and the discrepancies in the lepton (g−2)l's including the recent results at Fermilab E989. The RK(∗) and RD(∗) anomalies can be accommodated by the specific couplings for triplet and singlet leptoquarks, respectively, subject to the bounds from B→Kνν¯. We discuss the correlation...

6. A comprehensive study of vector leptoquark on the B-meson and Muon g-2 anomalies

Prof. Seong Chan Park (Yonsei University)

21/05/2021, 17:20

Theory

Recently reported anomalies in various B meson decays and also in the anomalous magnetic moment of muon (g − 2) motivate us to consider a particular extension of the standard model incorporating new interactions in lepton and quark sectors simultaneously. Our minimal choice would be leptoquark. In particular, we take vector leptoquark (U1) and comprehensively study all related observables.
