In this book, we simulated B-L model at Large Hadron Collider by using Monte Carlo simulation software. B-L model is one of many scenarios proposed to add an extension of the Standard Model of particle physics. These scenarios or models try to find a solution for many problems where the Standard Model can not solve it like dark matter, neutrino oscillation. B-L model predicts the existence of three new particles at the LHC. They are new neutral massive gauge boson, three heavy neutrinos (Right-Handed) and new heavy Higgs boson which is different from than Higgs of SM. We simulated these new...

There is a very strong interest to achieve stability from mode-locked laser beam for satellite laser radar station at Helwan by using a more simple, stable, and easier mode-locker. The energy stability of the laser output can improve the accuracy and reliability of the Helwan satellite laser ranging station ranging data remarkably. Normally, the saturable absorber dyes dissolved in dichlorethan has been used for Q-switching and Mode-locking of this system for many years. Decomposition and degradation of this type of mode-locking is a disadvantage simply because it is not permanent and needs...

The present book shows the following: (1)An example of a quality assurance procedure of the 3D-planning system in some physical aspects such as block fields, wedged fields, MU calculations and in homogeneity corrections. (2)An example of a quality assurance procedure of the 2D-planning system in some physical aspects such as MU calculations and in homogeneity corrections. (3)A conventional 2D-TP was compared to 3D-TP for 10 patients with breast and bladder cancer. Both types of treatment planning were performed with two tangential fields for patients with breast cancer and 3-fields technique...
