Coupling Constants and Brane Tensions from Anomaly Cancellation in M-theory
The theory of eleven dimensional supergravity on R × S/Z2 with super Yang-Mills theory on the boundaries is reconsidered. We analyse the general solution of the modified Bianchi identity for the four-form field strength using the equations of motion for the three-form and find that the four-form field strength has a unique value on the boundaries of R × S/Z2. Considering the local supersymmetry...
متن کاملBrane Tensions and Coupling Constants from within M-Theory
Reviewing the cancellation of local anomalies of M-theory on R × S/Z2 the Yang-Mills coupling constant on the boundaries is rederived. The result is λ = 2(2π)(4πκ) corresponding to η = λ/κ = 256π in the “upstairs” units used by Hořava and Witten and differs from their calculation. It is shown that these values are compatible with the standard membrane and fivebrane tensions derived from the M-t...
متن کاملAnomaly cancellation in M - theory
We show the complete cancellation of gauge and gravitational anomalies in the Mtheory of Horava and Witten using their boundary contribution, and a term coming from the existence of two and five-branes. A factor of three discrepancy noted in an earlier work is resolved. We end with a comment on flux quantization. e-mail: [email protected] In the M-theory of Horava and Witten [1] sever...
متن کاملAnomaly cancellation in M–theory on orbifolds
We present calculation of the anomaly cancellation in M–theory on orbifolds S/ZZ2 and T /ZZ2 in the upstairs approach. The main requirement that allows one to uniquely define solutions to the modified Bianchi identities in this case is that the field strength G be globally defined on S1 or T 5 and properly transforming under ZZ2. We solve for general G that satisfies these requirements and expl...
متن کاملRemarks on M-Theory Coupling Constants and M-Brane Tension Quantizations
In the absence of a complete M-theory, we gather certain quantum aspects of this theory, namely, M-2 and M-5 brane duality and their tension quantization rule 2κT2T5 = 2πn, the M-2 brane tension quantization T2 = ( (2π)/2κm )1/3 , supersymmetry, perturbative gauge and gravitational anomaly cancellations, and the half-integral quantization of [G/2π], and study the consistency among these quantum...
