Abstract: QCD has a rich phase structure in the extreme conditions of high temperature, large baryon density as well as strong magnetic field. It has been concluded that the QCD transition temperature decreases with increasing strength of the magnetic field. How to reconcile this fact with a larger value of chiral condensate and a consequent stronger breaking of the chiral symmetry in the nonzero magnetic field in the vacuum? Is this fact closely related to the inverse magnetic catalysis found near the transition temperature? If the magnetic field lives sufficiently long what is its impact on the fluctuations of conserved charges in the HIC experiments? The QCD transition with physical pions at zero baryon density does not possess any singular behavior and it is the transition with massless pions that has a criticality in the proximity of the chiral phase transition temperature. How does this criticality at vanishing quark masses relate to the criticality of the QCD critical end point that is being searched for in the HIC experiments? Higher-than-4th order fluctuations of proton numbers have been measured recently in the RHIC BES program. What is the baseline of these fluctuations from the thermal QCD in equilibrium? In this talk I will discuss recent results relevant to these questions from lattice QCD studies.
