Nair's Lecture Notes, second draft

I have left this draft for a long time. The second version is here. Materials that have been added and revised by Prof. Nair long before are also included in this version. Please let me know if there are any typos or corrections.

Particle data updated

Particle data screening system is revised with the latest set of data from Particle Data Group. The revised version is here. The total number of listed particles rises from 212 to 214, adding two new particles, K(0)*(700) and Delta(1900). The charges of these are (0,+) and (-,0,+,++), respectively. There are also two renamed particles, which are chi(c2)(2P) --> chi(c2)(3930) and Upsilon(1D) --> Upsilon(2)(1D).
