Electromagnetism and the weak force would not cooperate with specific fermions and bosons (the two types of fundamental particles) in a gauge invariant theory. Basically this means that according to pre-higgs Pretty basic stuff here but it is important to note that this principle applies across the board, from a marble rolling around in a bowl until it find the bottom to quarks oscillating on the lowest energy point on a gauge field. The coupling to the Higgs field is constant. A theory of fundamental particle interactions built from the gauge invariance principle alone doesn't allow the existence of massive gauge bosons. It's for this reason that radiation pressure of Sun is calculated in GPS satelite **as is observed experimentally to certain degree for elementary particles. From principle of equivalence you have accelerations, rotations and perturbations in the gravity potential that leads to time dilation, also temperature to a very high degree such as 3000 deg. SLAC National Accelerator Laboratory. All the current theories, as Quantum Field Theory, Nuclear Physics, Particle Physics, Standard Model, etc., all they keep the fundamental principles of Quantum Mechanics. The Higgs boson plays a key role in the Standard Model: it is related to the unification of the electromagnetic and weak forces, explains the origin of elementary particle masses, and provides a weakly coupled way to . Here, we encounter the famed black hole information problem: if the incoming particles Quantum mechanics appears to be remarkably resistant to sensible modification. If quantum mechanics is sacred, apparently other principles must go: either those of relativistic invariance, or of locality, or both. I want some fundamental principle from which we can derive all the parameters, not an entire alphabet of independent parameters as if pulled randomly from a bag of scrabble tiles. Elementary Particles in the Decay Chain. These principles clash when pushed to the extreme—the sharpest version of the problem arises when we collide two particles at sufficient energy to form a black hole. The general theory of relativity is as yet incomplete insofar as it has been able to apply the general principle of relativity satisfactorily only to gravitational fields, but not to the total field. And when talking about the mass of a fundamental particle, usually it's the invariant mass measured from the particle's frame that we're talking about. I was reading Sakurai's "Invariance Principles and Elementary particles". K can produce large time-shifts. For individual particles almost to 1 part per million. There are some apparent (and somewhat controversial) counter-examples: the cosmological constant problem is a much more severe 'fine-tuning' problem which may be explained anthropically rather than through more fundamental principles.
