abstract
The dark sector offers a compelling theoretical framework for addressing the nature of dark matter while potentially solving other fundamental problems in physics. This review focuses on light dark flavored sector models, which are those where the flavor structure of the interactions with the standard model is non-trivial and distinguish among different fermion families. Such scenarios feature flavor violation leading to unique experimental signatures, such as flavor-changing neutral current decays of heavy hadrons (kaons, $D$ and $B$ mesons, baryons) and leptons (muons and taus) with missing energy carried away by light dark-sector particles. In this article, we review their motivation, summarize current constraints, highlight discovery opportunities in ongoing and future flavor experiments, and discuss implications for astrophysics and cosmology.

How to Identify a Majoron: Effective Field Theories of Spontaneous Lepton Number Breaking
Seesaw Majoron models imply parameter-free correlations among Higgs, muon decay, and neutrino observables that can identify the neutrino mass mechanism.

$B\rightarrow K + \text{axion-like particles}$: effective versus UV-complete models and enhanced two-loop contributions
In the DFSZ axion model, the b to s a transition receives an unsuppressed two-loop contribution proportional to the scalar coupling lambda, which becomes important for tan beta above about 5.

Flavor-violating dark matter at MEG-II and Mu3e
Rare muon decays into a positron and two dark matter particles could let MEG-II and Mu3e probe lepton-flavor-violating dark matter interactions at TeV scales, with a radiative decay extending the reach to sub-MeV dark matter.

A framework for missing-energy searches with anomalous light vectors
For light U(1)X vectors coupled to anomaly-sensitive currents, Wess-Zumino coefficients are fixed by anomaly matching, which lets all missing-energy searches (K, B, D, Z) be mapped onto one (m_X,g_X) plane with minima...

Unified study of two-meson and axion-meson production from semileptonic tau decays within resonance chiral framework
Within a resonance chiral model, hadron resonances boost predicted tau decays into pion/K plus axion by factors of 7.5 and 19.2, with branching ratios and forward-backward asymmetries also predicted.
