Problems for the Standard Model The Standard Model: In Trouble? has been a pillar of fundamental physics for more than 30 years. It took decades to construct, and it is the crown jewel of 20th-century particle physics. In 1979, Sheldon Glashow, Abdus Salam and Steven Weinberg won the Nobel Prize for unifying the sectors of the theory comprising the weak subnuclear and electromagnetic forces in what is now known as the electroweak theory. The remaining sector, the strong interactions, is based on a so-called non-abelian gauge theory (a theoretical invention by R. L. Mills and C. N. Yang in 1954). The strong force holds the protons and neutrons together in a nucleus. The only fundamental force not included in the Standard Model of particle physics is gravity:
