Elementary Particle Physics
... (1) Mesons consist of qq and baryons of qqq. (2) Quarks carry a quantum number: isospin. The u, d u , d quarks represent different projections of the same quark (antiquark) in an internal isospin space, as p, n. When adding different isospins to form a hadron nature uses SU(2) symmetry to determ ...

The Standard Model of particle physics and beyond.
... In addition, the associated antiparticles. The only difference between generations lies in the (increasing) mass. Experimental status [Particle Data Group Review]. * All these particules have been observed. * Last ones: top quark (1995) and tau neutrino (2001). The Standard Model of particle physics ...

The wavelet approach to peak finding
... Now we can transform the invariant mass spectrum to G4 domain (a,b), find there bmax amax of the obtained surface and then fit it by the analytical formula for WG4(a,b;x0,σ)g starting fit from x0= bmax and σ = amax/3. To test this approach we prepared the simulated spectrum of invariant mass, consis ...

SYMMETRIES IN PHYSICS: Philosophical Reflections
... The formal context of Noether’s theorems is Lagrangian field theory wherein equations of motion are obtained through a variational procedure (Hamilton’s principle) from the action integral, S = L d x. Noether’s theorems are discussed in detail in Earman (2002) and Brading and Brown (this volume). N ...
