Several members of the IFAE-ATLAS group are attending, with one of them giving a talk at a parallel session:

• “The HL-LHC Upgrade of the ATLAS Tile Hadronic Calorimeter ” - Danijela Bogavac

At this conference, the ATLAS Collaboration is releasing a total of 26 new results using the full Run 2 dataset (results being added as the public webpages are unembargoed):

The IFAE-ATLAS group has made strong contributions to three new results:

• “Combination and summary of ATLAS dark matter searches using 139 fb−1 of √s = 13 TeV pp collision data and interpreted in a two-Higgs-doublet model with a pseudoscalar mediator”, ATLAS-CONF-2021-036
• “Search for a light charged Higgs boson in t→H±b decays, with H±→cb, in the lepton jets final state in proton-proton collisions at √s=13 TeV with the ATLAS detector”, ATLAS-CONF-2021-037
• “Search for the single production of vector-like T quarks decaying into tH and tZ with the ATLAS detector”, ATLAS-CONF-2021-040

The GW group is contributing a talk to EPS-HEP 2021

• “Implications for first-order cosmological phase transitions and the formation of primordial black holes from the third LIGO-Virgo observing run ” - Alba Romero

The theory group is contributing a talk to EPS-HEP 2021

• “Quality tests for the Heavy QCD axion ” - Ricardo Zambujal
