An Introduction to the Standard Model of Particle Physics. 2007. It does not assume previous QFT knowledge, but it only reviews it somewhat superficially. The thorough discussion is on particle …

2012年1月11日 · $\begingroup$ @QuantumDot: It's harshness is accurate, the field theorists didn't understand S-matrix, and drove all the practitioners out of physics (including many early …

2023年12月31日 · In nuclear physics, while studying gamma decay (Nuclear physics, Roy and Nigam, 1st ed, pp 450) I have read that the parity of photons depends on the type of multipole …

Particle physics is the study of the fundamental forces of nature as they are embodied in the interactions of elementary and composite particles at high energies and short time and …

For example, a spin 1/2 particle's wavefunction will gain a minus sign under a 360 degree rotation, as the rotation changes the complex phase of the wavefunction. The particle's chirality …

I'm reading Thomson, Modern Particle Physics, and in chapter 16 author says that the decay width of the Z boson is $\Gamma_Z =2.452 \pm 0.0023 \,\mathrm{GeV}$.

2011年4月21日 · The primary example in this category is CP-violation, which strongly limits the range of allowed models of new physics up to scales of several TeV. There are good a priori …

All of particle physics pretty much comes down to calculating decay rates or scattering cross sections. In either case, the quantity you calculate is a function of the momenta of the initial …

2013年5月16日 · A particle is a state, and a state is a particle. (More precisely, particles are eigenstates of the operator of energy - in the low-energy case - or the operator of mass - in the …

Their couplings are by soft-particle theorems. The eta-prime is their frustrated friend, weighed down by the instanton fluid. The rho and omega are the gauge fields for flavor SU(2), and …
