Axion and axion-like particle models are typically affected by a strong\nfine-tuning problem in conceiving the electroweak and the Peccei-Quinn breaking\nscales. Within the context of the Minimal Linear \σ Model, axion-like\nparticle constructions are identified where this hierarchy problem is solved,\naccounting for a TeV Peccei-Quinn breaking scale and a pseudoscalar particle\nwith a mass larger than 10 MeV. Potential signatures at colliders and\nB-factories are discussed.\n
