The 't Hooft symbol is a collection of numbers which allows one to express the generators of the SU (2) Lie algebra in terms of the generators of Lorentz algebra. The symbol is a blend between the Kronecker delta and the Levi-Civita symbol. It was introduced by Gerard 't Hooft.
µν, the anti self-dual t’ Hooft symbols, which read: ¯σaµν = σ¯a44 = 0 σ¯a4ν = δaν for ν= 1,2,3 σ¯aµ4 = −δaµ for µ= 1,2,3 σ¯aµν = ǫaµν for µ,ν= 1,2,3. (2.5) 2.2 Decomposition of the twisted self-dual equation
24. Juli 2020 · where are the 't Hooft symbols. As we have shown here, the form invariance condition strongly restricts the ansatz. Let us emphasize this point by another example. For instance, one may write an expression with two types of 't Hooft symbols:
26. Juni 2021 · where g g is the coupling constant and Φ Φ is a N × N N × N hermitian matrix. He shows that the large- N N limit of this model only makes sense when we consider the 't Hooft parameter. λ't Hooft = g2N, λ 't Hooft = g 2 N, and take the N → ∞ N → ∞ limit while keeping λ't Hooft λ 't Hooft fixed.
26. Apr. 2021 · We compute by supersymmetric localization the expectation values of half-BPS ’t Hooft line operators in \ ( \mathcal {N} \) = 2 U ( N ), SO ( N ) and USp ( N ) gauge theories on S1 × ℝ 3 with an Ω-deformation.
