Search for axionlike particles produced in e+ e− collisions at Belle II

We present a search for the direct production of a light pseudoscalar 𝑎 decaying into two photons with the Belle II detector at the SuperKEKB collider. We search for the process 𝑒+⁢𝑒−→𝛾⁢𝑎, 𝑎→𝛾⁢𝛾 in the mass range 0.2<𝑚𝑎<9.7 GeV/⁢𝑐2 using data corresponding to an integrated luminosity of (445±3...
