CTEQ-TEA group updates: Photon PDF and Impact from heavy flavors in the CT18 global analysis
We discuss recent CTEQ-TEA group activities after the publication of the CT18 global analysis of parton distribution functions (PDFs) in the proton. In particular, we discuss a new calculation for the photon content in the proton, termed as CT18lux and CT18qed PDFs,
and the impact of novel charm- and bottom-quark production cross section measurements at HERA on the CT18 global analysis.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
