In M-theory, is a baryon a D4 brane with three strings?

[Nav]

I've read in a few string theory documents that have 10d spacetime that a baryon is a D4 brane with three strings (each being a quark), but what about in M theory?

In M theory, baryons are still described as D4 branes with three strings, each representing a quark. However, M theory goes beyond string theory by incorporating an additional dimension, making it an 11-dimensional theory. This additional dimension allows for the existence of additional branes, such as M2 and M5 branes, which can also play a role in the description of baryons.

In M theory, baryons can also be described as bound states of M2 and M5 branes, with the strings representing the interactions between these branes. This adds another level of complexity to the description of baryons in M theory.

Overall, the concept of baryons as D4 branes with three strings remains consistent in M theory, but the additional dimension and presence of other branes adds more complexity to the understanding of baryons in this theory. Further research and developments in M theory may provide even more insights into the nature of baryons and their role in the universe.
