TLDR
In this article, an axion-like particle (ALP) was used to solve the problem of the inconsistency among the measurements of the branching ratios and asymmetries of the four $B\ensuremath{\rightarrow}\ensureMath{\pi}K$ decays.Abstract:
We offer a new solution to an old puzzle in the penguin-dominated $B\ensuremath{\rightarrow}\ensuremath{\pi}K$ decays. The puzzle is the inconsistency among the measurements of the branching ratios and $CP$ asymmetries of the four $B\ensuremath{\rightarrow}\ensuremath{\pi}K$ decays: ${B}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{K}^{0}$, ${B}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}{K}^{+}$, ${B}_{d}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{K}^{+}$, ${B}_{d}^{0}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}{K}^{0}$. We solve the $B\ensuremath{\rightarrow}\ensuremath{\pi}K$ puzzle by considering the effect of an axionlike particle (ALP) that mixes with the ${\ensuremath{\pi}}^{0}$ and has mass close to the ${\ensuremath{\pi}}^{0}$ mass. We show that the ALP can also explain the anomalies in the electron and muon anomalous magnetic moments.read more

Muon and electron $$g-2$$ anomalies in a flavor conserving 2HDM with an oblique view on the CDF $$M_W$$ value
TL;DR: In this article , a modified lepton sector model is considered for the type I or type X two Higgs doublets model with a modified Lepton sector, where the new lepton Yukawa couplings are completely decoupled from lepton mass proportionality.

TL;DR: In this article , it was shown that there is no parameter space for such models to solve both the $(g-2)_\mu$ and $B$ anomalies simultaneously, after taking into account existing constraints from $\tau \to \mu \gamma$, $\tAU \to 3 \mu$, neutrino trident and $b_s - \bar B_s$ data.

Thermal Leptophilic Light Vector Dark Matter with Spinor Mediator and Muon (g-2) Anomaly
TL;DR: In this paper , the authors revisited phenomenology of a light MeV scale vector dark matter in a leptophilic extension of standard model while a new spinor field plays the role of mediator.

CP Conservation in the Presence of Pseudoparticles
R.D. Peccei,Helen R. Quinn +1 more
TL;DR: In this paper, the authors give an explanation of the conservation of strong interactions which includes the effects of pseudoparticles, and they find it is a natural result for any theory where at least one flavor of fermion acquires its mass through a Yukawa coupling to a scalar field which has nonvanishing vacuum expectation value.

A new light boson
TL;DR: In this article, it was pointed out that a global U(1) symmetry, introduced in order to preserve the parity and time-reversal invariance of strong interactions despite the effects of instantons, would lead to a neutral pseudoscalar boson, the "axion", with mass roughly of order 100 keV to 1 MeV.

Problem of Strong $P$ and $T$ Invariance in the Presence of Instantons
TL;DR: In this article, the color gauge theory of strong interactions without arbitrary adjustment of parameters is analyzed and several possibilities are identified, including one which would give a remarkable new kind of very light, long-lived pseudoscalar boson.

TL;DR: In this article, it was shown that strong CP conservation remains a natural symmetry if the full Lagrangian possesses a chiral U(1)-invariant invariance, which is the case for weak CP conservation.
