Higgs to fermion decays / Cuevas Maestro, Javier (Oviedo U.) /ATLAS and CMS Collaborations
The discovery of the Higgs boson in 2012 by ATLAS and CMS collaborations fulfilled one of the main aims of the LHC, identifying a mass generation mechanism for the Standard Model (SM) giving us access to a new sector of the SM. Among others they are the Yukawa couplings, a less experimentally constrained interaction to investigate. [...]

Search for a resonance decaying into a scalar particle and a Higgs boson in the final state with two bottom quarks and two photons in proton-proton collisions at a center of mass energy of 13 TeV with the ATLAS detector / ATLAS Collaboration
A search for the resonant production of a heavy scalar $X$ decaying into a Higgs boson and a new lighter scalar $S$, through the process $X \to S(\to bb) H(\to \gamma\gamma)$, where the two photons are consistent with the Higgs boson decay, is performed. [...]

Search for the non-resonant production of Higgs boson pairs via gluon fusion and vector-boson fusion in the $b\bar{b}\tau^+\tau^-$ final state in proton-proton collisions at $\sqrt{s} = 13$ TeV with the ATLAS detector / ATLAS Collaboration
A search for the non-resonant production of Higgs boson pairs in the $HH\rightarrow b\bar{b}\tau^+\tau^-$ channel is performed using 140 fb$^{-1}$ of proton-proton collisions at a centre-of-mass energy of $13$ TeV recorded by the ATLAS detector at the CERN Large Hadron Collider. [...]

tt+X measurements by CMS and ATLAS / Alvarez Gonzalez, Barbara (ICTEA, Oviedo)
These proceedings present the observation of the 4-top production process and the latest results of the production of top-quark pairs associated with W and $\gamma$ bosons ($t\bar{t}W$ and $t\bar{t}\gamma$) and b jets ($t\bar{t}b\bar{b}$) at a collision energy of 13 TeV carried out by the CMS and ATLAS Collaborations..
