Searches for Large Extra Dimensions, Leptoquarks and Heavy Quarks at CMS.

Sushil Singh Chauhan
We present results from several searches for physics beyond the standard model involving large extra dimensions, leptoquarks, and heavy quarks at $\sqrt s =$ 7 TeV with the CMS experiment. Many different final states are analyzed using the data collected in 2010 and 2011 corresponding to an integrated luminosity up to $5.0fb^{-1}$. The results are used to set new limits on the scale of large extra dimensions and on the masses of leptoquarks and heavy...
