Basic ideas of Particle Physics.. A Klong Meson
Another example of importance of Particle Physics as is understood by the general public is Blackhole. Well see blackhole is not a particle-phyics idea but the general public knows LHC is a particle-physics lab which produces blackholes that can engulf the world. Such was the paranoia in the year 2008 before LHC had started banging…

Basic concepts of Monte Carlo and reconstruction.
This scheme as you could see is only a flip-flop and works to check if this works and my toy Monte Carlo proved that it does. But in real situations this Dzero mass constraint is used to recover the Klong 4-vector which also means we have the Dzero full-info now. But we input some Dzero…

Feynman Diagram of Higgs Boson Production.
This is a copy of the diagram from Wikipedia. I produced this using codes developed by me as previously instructed here with other examples. — What to do when its 2 am around here, you are fresh but nowhere to go. Here is the code: % Feynman diagram % Requires PGF >= 2.0 \documentclass{article} \usepackage[latin1]{inputenc}…

symmetry, unitarity, symmetry breaking.
Now think of an electron. The force here is such that the electron will change into something else. It may or may not change, just like the man. In one case a force that describes the electron is a symmetry force. In another its a broken symmetry. Broken symmetries can be added to symmetries to…

Spontaneous symmetry breaking of electroweak force and Higgs
Higgs: When they introduce new scalar fields [new gauge] the symmetry of electroweak forces are broken. That is, NO MORE electromagnetic and weak forces are but the same force. In that case the scalar fields show up as energy with masses of the particles. This is quite easy to understand. The 4-vectors always have scalar…
