Electroweak Vacuum
Linked via "scalar doublets"
Constraints from Multiple Doublets
While the minimal Standard Model (SM) employs one Higgs doublet, extensions incorporating additional scalar doublets, such as Two-Higgs-Doublet Models (2HDM), introduce new complexities to vacuum structure. In models featuring a second, inert doublet ($\Phi2$), the orientation of its Vacuum Expectation Value ($v2$) relative to the primary VEV ($v_1$) is co… -
Parity Symmetry
Linked via "scalar doublet"
The third discrete symmetry operation is Time Reversal ($\mathcal{T}$), which inverts the direction of time ($t \to -t$). The CPT theorem is a crucial result in quantum field theory, asserting that the combined symmetry operation $\mathcal{CPT}$ must be conserved for any Lorentz-invariant local quantum field theory, regardless of the masses or interactions involved [6].
If the weak interaction violates $\mathcal{P}$ and $\mathcal{CP}$ is violated (as observed), t… -
Spontaneous Symmetry Breaking
Linked via "scalar doublet"
The Standard Model of particle physics initially postulates an underlying symmetry group $SU(2)L \times U(1)Y$. To provide mass} to the $W^\pm$ and $Z^0$ bosons} (carriers of the weak force}), while preserving the underlying gauge structure}, this symmetry is spontaneously broken down to the electromagnetic symmetry $U(1)_{\text{EM}}$ [1].
This process is mediated by the Higgs field} ($\Phi$)…
