The isospin and strangeness determine this quantity for hadrons in a formula developed by Okubo and Gell-Mann. When this quantity (-5[1])equals (-5[1])zero, the Dirac equation reduces to the Weyl [vile] equation. Spontaneous (-5[1])symmetry breaking creates (15[1])bosons with a zero value of this (-5[1])quantity according (-5[1])to Goldstone’s (15[2]-5[1])theorem. In a formula named for this quantity, Coulomb, asymmetry, and pairing terms are used to represent the liquid drop model; that (10[2])(*) “semi-empirical” formula is (10[1])used to calculate the nucleus’s namesake “defect” in this (10[1])quantity. A (10[1])Millennium (10[1])Prize (10[1])problem (10[1])involves determining (10[1])whether Yang-Mills theory has a “gap” in this quantity. Kinetic energy equals momentum squared over 2 times this (10[2])quantity. For 10 points, Albert Einstein stated (10[1])that what (10[1])quantity equals (-5[1])energy (-5[1])over the speed of light (10[1])squared? (10[6]0[1])■END■
