abstract = {Recently it was discovered that the jump in the specific heat at the 

 superconducting transition in pnictide superconductors is proportional 

 to the superconducting transition temperature to the third power, with 

 the superconducting transition temperature varying from 2 to 25 K 

 including underdoped and overdoped cases. Relying on standard scaling 

 notions for the thermodynamics of strongly interacting quantum critical 

 states, it is pointed out that this behavior is consistent with a normal 

 state that is a quantum critical metal undergoing a pairing instability.},
