Correlating gravitational waves with W-boson mass, FIMP dark matter, and majorana seesaw mechanism

X Liu, SY Guo, B Zhu, Y Li - Science Bulletin, 2022 - Elsevier
We study a minimal extension of the standard model by introducing three right-handed
neutrinos and a new scotogenic scalar doublet, in which the mass splittings between neutral …

Footprints of new physics in transitions

ZR Huang, Y Li, CD Lu, MA Paracha, C Wang - Physical Review D, 2018 - APS
In this work, we perform a combined analysis of the R (D), R (D*), and R (J/ψ) anomalies in a
model-independent manner based on the general framework of the four-fermion effective …

sizable new physics contribution to the electron and muon anomalous magnetic moments …

On lepton flavour universality in semileptonic Bc→ ηc, J/ψ decays

D Leljak, B Melić, M Patra - Journal of High Energy Physics, 2019 - Springer
A bstract We discuss B c→ η c and B c→ J/ψ semileptonic decays within the Standard Model

transitions in the standard model effective field theory

QY Hu, XQ Li, YD Yang - The European Physical Journal C, 2019 - Springer
Abstract The R (D^(*)) R (D (∗)) anomalies observed in B → D^(*) τ ν B→ D (∗) τ ν decays
have attracted much attention in recent years. In this paper, we study the B → D^(*) τ ν B→ D …

[HTML][HTML] Revisit to the b→ cτν transition: in and beyond the SM

K Cheung, ZR Huang, HD Li, CD Lü, Y Mao, RY Tang - Nuclear Physics B, 2021 - Elsevier
We perform an analysis of the b→ c τ ν data, including R (D (⁎)), R (J/ψ), P τ (D⁎) and
FLD⁎, within and beyond the Standard Model (SM). We fit the B→ D (⁎) hadronic form …

Investigation of effects of new physics in decay

XL Mu, Y Li, ZT Zou, B Zhu - Physical Review D, 2019 - APS
Recent experimental results of R (D (*)) deviate from the standard model (SM) by 3.1 σ,
suggesting a new physics (NP) that affects the b→ c τ ν¯ τ transition. Motivated by this, we …

Unification of flavor SU (3) analyses of heavy hadron weak decays

XG He, YJ Shi, W Wang - The European Physical Journal C, 2020 - Springer
Analyses of heavy mesons and baryons hadronic charmless decays using the flavor SU (3)
symemtry can be formulated in two different forms. One is to construct the SU (3) irreducible …

Simple model for large CP violation in charm decays, B-physics anomalies, muon g− 2 and dark matter

L Calibbi, T Li, Y Li, B Zhu - Journal of High Energy Physics, 2020 - Springer
A bstract We present a minimal extension of the Standard Model that can simultaneously
account for the anomalies in semi-leptonic B meson decays and the muon g− 2, give large …

-meson decays into plus a light meson in the improved perturbative QCD formalism

X Liu - Physical Review D, 2023 - APS
In the wake of measurements on B c+→ J/ψ K+, B c+→ J/ψ π+ π-π+, and B c+→ J/ψ K+ K-π+
at Large Hadron Collider experiments, we propose to study the decays B c+→ J/ψ M+ …
