Next Generation Higgs Bosons: Theory, Constraints and Discovery Prospects at the Large Hadron Collider

Understand

Particle physics model building within the context of string theory suggests that further copies of the Higgs boson sector may be expected.

• Concerns regarding tree-level flavor changing neutral currents are easiest to allay if little or no couplings of next generation Higgs bosons are allowed to Standard Model fermions.
• We detail the resulting general Higgs potential and mass spectroscopy in both a Standard Model extension and a supersymmetric extension.
• We present the important experimental constraints from meson-meson mixing, loop-induced $b\to s\gamma$ decays and LEP2 direct production limits.
