Title: "Model-independent analysis of scenarios with single 
and multiple vector-like quarks" 

Abstract: The discovery at the LHC of a particle compatible 
with the Higgs boson may open a window on scenarios of new 
physics beyond the Standard model. In fact, searches for new 
heavy fermionic states have been undertaken both at Tevatron 
and at the LHC, but no evidence has emerged so far, pushing 
the mass bounds above 600 GeV, depending on specific scenarios. 
Vector-like quarks are however predicted in various scenarios 
of new physics, and their peculiar signatures from both pair 
and single production are worth investigating in detail. 
I will illustrate the phenomenology of vector-like quarks 
from a model-independent point of view, describing a minimal 
scenario with the inclusion of a new vector-like state which 
couples to all SM quarks through Yukawa interactions and 
perspectives for a combined analysis of LHC data to test 
non-minimal scenarios with multiple vector-like quarks.
