Over the past decade, the LHCb and CMS experiments have reported persistent tensions in several branching fractions and angular observables of exclusive $b \to s \mu^+\mu^-$ decays. Taken together, these discrepancies exceed the five-standard-deviation level. However, their interpretation remains the subject of active debate, particularly regarding the size and treatment of nonperturbative QCD...

We study the low-energy behavior of gauge couplings in the presence of dynamical scalar backgrounds. In weakly coupled, renormalizable four-dimensional theories, gauge invariance restricts the dependence on the scalar background to be logarithmic. The gauge coupling evolution in these scenarios can be entirely described by the renormalization-group running with dynamical mass thresholds....

Dark matter (DM) can be gravitationally captured around a massive compact object, forming a dense halo. If primordial black holes (PBHs) exist, surrounding dark matter particles can be accreted through gravitational attraction, leading to the formation of a DM halo with a steep spike profile near the PBH.
If the dark matter consists of axions or axion-like particles (ALPs), the high number...
