Recent spectroscopy results from the ATLAS and CMS experiments at the LHC are shedding new light on the hadronic spectrum. These include the first precise measurements of the excited vector mesons $B^{*+}$, $B^{*0}$, and $B^{*0}_s$, alongside the observation of a new family of tetraquark candidates in the di-$J/\psi$ channel. CMS has further determined the spin-parity quantum numbers of this new family to be $J^{PC} = 2^{++}$. Both collaborations have extended these studies to other decay channels, such as $J/\psi + \psi(2S)$. Collectively, these results underscore the LHC's unparalleled capability to explore the spectrum of hadronic states, providing crucial insights into non-perturbative QCD and the quark model.
