Search for Higgs boson decays into two new low-mass spin-0 particles in the 4b channel with the ATLAS detector using pp collisions at √s=13 TeV has been submitted to Phys. Rev. D.
This paper describes a search for beyond the Standard Model decays of the Higgs boson into a pair of new spin-0 particles (a) subsequently decaying into b-quark pairs, H->aa->(bb)(bb). The search targets the production mode where the Higgs boson is produced in association with a Z boson, and focuses on the challenging mass regime of 15<m(a)<30 GeV, which yields collimated a->bb decay products requiring the development of a novel strategy for their identification.
From the IFAE-ATLAS team, Aurelio Juste has contributed to the analysis.

The European Physical Society conference on high energy physics 2021 (EPS-HEP 2021), one of the most important conferences in HEP of the year, is taking place online this week. Three IFAE groups are participating:
New ATLAS publication
June 30, 2021
“Measurement of the tttt production cross section in pp collisions at sqrt(s)=13 TeV with the ATLAS detector” has been submitted to JHEP. Members of the IFAE-ATLAS team (Aurelio Juste, Nicola Orlando, and Anil Sonay) have played a leading role in this publication, from designing the analysis strategy to the final multivariate technique and statistical analysis employed.
