Search for direct production of GeV-scale resonances decaying to a pair of muons in proton-proton collisions at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
A search for direct production of low-mass dimuon resonances is performed using $ \sqrt{s}= $ 13 TeV proton-proton collision data collected by the CMS experiment during the 2017-2018 operation of the CERN LHC with an integrated luminosity of 96.6 fb$^{-1}$. [...]

Search for the exclusive $W$ boson hadronic decays $W^{\pm}\to\pi^{\pm}\gamma$, $W^{\pm}\to K^{\pm}\gamma$ and $W^{\pm}\to\rho^{\pm}\gamma$ with the ATLAS detector / ATLAS Collaboration
A search for the exclusive hadronic decays $W^{\pm}\to \pi^{\pm}\gamma$, $W^{\pm}\to K^{\pm}\gamma$ and $W^{\pm}\to \rho^{\pm}\gamma$ is performed using up to $140\, \text{fb}^{-1}$ of proton-proton collisions recorded with the ATLAS detector at a center-of-mass energy of $\sqrt{s}=13\,\text{TeV}$.
