Tidal effects away from the equatorial plane in Kerr backgrounds
/ Banerjee, Pritam ; Paul, Suvankar ; Shaikh, Rajibul ; Sarkar, Tapobrata
Tidal effects on selfgravitating Newtonian stars rotating around a Kerr black hole in stable spherical orbits away from the equatorial plane are exemplified by a nonvanishing Carter's constant, and are substantially different from those on the equatorial plane. [...]

A variant twoHiggs doublet model with a new Abelian gauge symmetry
/ Chen, ChuanRen ; Chiang, ChengWei ; Lin, KuoYen
We consider a twoHiggs doublet model extended with a broken Abelian gauge symmetry under which all Standard Model (SM) quarks, fourth generation fermions and a new SMsinglet scalar boson are charged. [...]

UV contributions to energy of a static quarkantiquark pair in large β 0 approximation
/ Hayashi, Yuuki ; Sumino, Yukinari
The total energy of a static quarkantiquark pair Etot(r)=2mpole+VQCD(r) is known to include O(ΛQCD3r2) and O(ΛQCD3/m‾2) renormalon uncertainties in the large β0 approximation, after canceling O(ΛQCD) renormalons. [...]

Symmetry restoration in the meanfield description of protonneutron pairing
/ Romero, A.M. ; Dobaczewski, J. ; Pastore, A.
We show that the symmetryrestored paired meanfield states (quasiparticle vacua) properly account for isoscalar versus isovector nuclear pairing properties. [...]
