Physicists find new way to detect hidden Higgs particles at world's largest collider
Researchers have identified a promising new detection method for lightweight Higgs bosons at the Large Hadron Collider, potentially revealing physics beyond the Standard Model. The discovery could help unlock fundamental questions about particle physics and validate theoretical predictions that have remained experimentally elusive.
Originaltitel: Hunting light Higgses at the LHC in the context of the 2HDM Type-I
<p>We show the reinterpretation of existing searches for exotic decays of the Standard Model (SM)-like Higgs, H -> aa (hh), in various final states, in the framework of the 2-Higgs Doublet Model (2HDM) Type-I. We then explore a new search for such light Higgses, a and h, at the Large Hadron Collider (LHC) Run 3 for an integrated luminosity of 300 fb(- 1). After performing a scan over the model parameters, we found that the inverted scenario of Type-I offers a new promising signal in the form of the following cascade decays: H -> Z*a -> Z*Z*h -> b (b) over bar mu(-)mu(+)jj. We investigate then its significance through a full Monte Carlo (MC) simulation down to the detector level.</p>
