Strings May Tie Quantum Gravity to Quantum Chromodynamics
AUG 01, 1998
Might we learn more about the strong interactions by studying string theory? That’s one possibility raised by recent work showing that string theories and gauge field theories are flip sides of the same coin.

Although string theorists explore bizarre multidimensional spaces filled with tiny loops and membranelike objects, they are ultimately seeking a description of the real world. They may have come close with a recent hypothesis that links a ten‐dimensional string theory to a gauge field theory in the four dimensions of our ordinary world. The theorists’ great hope is that this connection extends to the specific gauge theory describing quantum chromodynamics (QCD), which governs the strong interactions.
