Can effective muon g-2 depend on the gravitational potential?
H. Nikolic
Contrary to the claim in a series of recent papers, we show that it cannot. A source of the error in those papers is misinterpretation of coordinate time as a physical time.
A prediction of string theory testable at low energies
H. Nikolic
Superstring theory involves a single unifying superstring current for bosons and fermions that in the low-energy limit generalizes the Klein-Gordon (not the Dirac) current. By adop…
Unparticle as a particle with arbitrary mass
H. Nikolic
The unparticle field operator can be expanded in terms of creation and destruction operators corresponding to particles with a continuous mass spectrum. Hence, when the 4-momentum…
Superluminal pions in a hadronic fluid
Neven Bilic, Hrvoje Nikolic
We study the propagation of pions at finite temperature and finite chemical potential in the framework of the linear sigma model with 2 quark flavors and colors. The velocity…
Physical stability of the QED vacuum
H. Nikolic
The possibility of electron-positron pair creation by an electric field is studied by using only those methods in field theory the predictions of which are confirmed experimentally…
Chiral-symmetry restoration in the linear sigma model at nonzero temperature and baryon density
Neven Bilic, Hrvoje Nikolic
We study the chiral phase transition in the linear sigma model with 2 quark flavors and colors. One-loop calculations predict a first-order phase transition at both and…
