Explaining the DAMPE $e^{+} e^{-}$ excess using the Higgs triplet model with a vector dark matter

Chuan-Hung Chen, Cheng-Wei Chiang, Takaaki Nomura

We explain the $e^{+} e^{-}$ excess observed by the DAMPE Collaboration using a dark matter model based upon the Higgs triplet model and an additional hidden $S U (2)_{X}$ gauge symmetry.…

Model with a gauged lepton flavor SU(2) symmetry

Cheng-Wei Chiang, Koji Tsumura

We propose a model having a gauged $S U (2)$ symmetry associated with the second and third generations of leptons, dubbed $S U (2)_{μτ}$ , of which $U (1)_{L_{μ} - L_{τ}}$ is an Abelian subgro…

Three-body decays $B \to ϕ (ρ) K γ$ in perturbative QCD approach

Chao Wang, Jing-Bin Liu, Hsiang-nan Li +1

We study the three-body radiative decays $B \to ϕ (ρ) K γ$ induced by a flavor-changing neutral current in the perturbative QCD approach. Pseudoscalar-vector ( $P V$ ) distribution ampli…

Current Status of Top-Specific Variant Axion Model

Cheng-Wei Chiang, Hajime Fukuda, Michihisa Takeuchi +1

The invisible variant axion model is very attractive as it is free from the domain wall problem. This model requires at least two Higgs doublets at the electroweak scale, with one…

Possible open-charmed pentaquark molecule $Ω_{c} (3188)$ --- the $D Ξ$ bound state --- in the Bethe-Salpeter formalism

Chao Wang, Liang-Liang Liu, Xian-Wei Kang +2

We study the $S$ -wave $D Ξ$ bound state in the Bethe-Salpeter formalism in the ladder and instantaneous approximations. With the kernel generated by the hadronic effective Lagrangia…

New analysis of $η π$ tensor resonances measured at the COMPASS experiment

A. Jackura, C. Fernandez-Ramirez, M. Mikhasenko +232

We present a new amplitude analysis of the $η π$ $D$ -wave in $π^{-} p \to η π^{-} p$ measured by COMPASS. Employing an analytical model based on the principles of the relativistic $S$ -mat…

Masses of Scalar and Axial-Vector B Mesons Revisited

Hai-Yang Cheng, Fu-Sheng Yu

The SU(3) quark model encounters a great challenge in describing even-parity mesons. Specifically, the $q q ˉ$ quark model has difficulties in understanding the light scalar meso…

Revisiting the factorization theorem for $ρ γ^{*} \to π (ρ)$ at twist 3

Shan Cheng, Ya-lan Zhang, Jun Hua +2

We revisit the proof of the perturbative QCD factorization for the exclusive processes $ρ γ^{⋆} \to π (ρ)$ at the two-parton twist-3 level. It is pointed out that the residual co…

Higgs boson pair productions in the Georgi-Machacek model at the LHC

Jung Chang, Chuan-Ren Chen, Cheng-Wei Chiang

Higgs bosons pair production is well known for its sensitivity to probing the sign and size of Higgs boson self coupling, providing a way to determine whether there is an extended…
