Towers and hierarchies in the Standard Model from Emergence in Quantum Gravity
Published 2023-10-01“…In particular, the EW scale and that of the extra dimension fulfill m 0 M EW ≲ 102 V 0 1 / 4 $$ {V}_0^{1/4} $$ M p , thus relating the EW hierarchy problem to that of the c.c. Hence, all fundamental scales may be written as powers of the c.c., i.e. m • ∼ V 0 δ M p 1 − 4 δ $$ {V}_0^{\delta }{M}_p^{1-4\delta } $$ . …”

Search for heavy ZZ resonances in the 4ℓ final state with the ATLAS detector and identifying muons in the ATLAS calorimeter using machine learning
Published 2021“…</p> <p>The search concerns signatures of an extended Higgs sector motivated by extensions to the Standard Model of particle physics that address the large discrepancy between the gravitational and the electroweak energy scales known as the hierarchy problem. A search for heavy ZZ resonances decaying to 4ℓ, where ℓ stands for either an electron or a muon, is conducted in the mass range between 200 and 2000 GeV using 139 fb-1 of proton-proton collision data collected at a centre-of-mass energy of √s=13 TeV with the ATLAS detector during 2015—2018 data-taking at the LHC. …”

High-temperature electroweak symmetry non-restoration from new fermions and implications for baryogenesis
Published 2020-09-01“…We show that such an effect can also be induced by new singlet fermions which on the other hand have the advantage of not producing unstable directions in the scalar potential at tree level, nor bringing additional severe hierarchy problems. As temperature drops, such a high-temperature breaking phase may continuously evolve into the zero-temperature breaking phase or the two phases can be separated by a temporary phase of restored symmetry. …”
