Physicists chart path to detect theorized heavy Higgs particle at world's largest collider
Researchers have mapped out how to find a previously undetected type of Higgs boson weighing around 400 billion electron volts using the Large Hadron Collider's next-generation runs. The discovery would validate an extended physics theory and could reshape understanding of fundamental particle interactions—with implications for next-generation physics experiments and the future direction of particle research funding.
Originaltitel: Searching for a heavy neutral CP-even Higgs boson in the BLSSM at the LHC Run 3 and HL-LHC
<p>The detection of a heavy neutral CP-even Higgs boson of the B - L Supersymmetric Standard Model (BLSSM), h', with m(h) similar or equal to 400 GeV, at the Large Hadron Collider (LHC) for a center-of-mass energy of root s = 14 TeV, is investigated. The following production and decay channels are considered: gg -> h'. ZZ -> 4l and gg -> h' -> W+W- -> 2l + E(sic)(T) (with E(sic)(T) being the Missing Transverse Energy (MET)), where l = e, mu, with integrated luminosity L-int = 300 fb(-1) (Run 3). Furthermore, we also look into the di-Higgs channel gg -> h' -> hh -> b (b) over bar gamma gamma at the High-Luminosity LHC (HL-LHC) with an integrated luminosity of L-int = 3000 fb(-1). We demonstrate that promising signals with high signal-to-background statistical significance (S/root B) can be obtained through the three aforementioned channels.</p>
