On the origin of the peak of the sound velocity for isospin imbalanced strongly interacting matter

Physics Letters B
We study the properties of a system composed of strongly interacting matter with an isospin imbalance, using as an effective description of QCD the two-flavor Linear Sigma Model with quarks.

Exothermic isospin-violating dark matter after SuperCDMS and CDEX

Physics Letters B, 2015
We show that exothermic isospin-violating dark matter (IVDM) can make the results of the latest CDMS-Si experiment consistent with recent null experiments, such as XENON10, XENON100, LUX, CDEX, and SuperCDMS, whereas for the CoGeNT experiment, a strong ...

Impact parameter dependence of isospin effects on the mass dependence of balance energy

, 2010
We study the effect of isospin degree of freedom on the balance energy as well as its mass dependence throughout the mass range 48-270 for two sets of isobaric systems with N/Z = 1 and 1.4 using isospin-dependent quantum molecular dynamics (IQMD) model ...

Isospin influences on particle emission and critical phenomenon in nuclear dissociation

, 2000
Features of particle emission and critical point behavior are investigated as functions of the isospin of disassembling sources and temperature at a moderate freeze-out density for medium-size Xe isotopes in the framework of isospin dependent lattice gas

Opening windows with isospin-violating dark matter

Physics Letters B
We consider the effect of isospin-violating dark matter-nucleon interactions on direct detection constraints in the regime of small dark matter mass and large scattering cross section.

Weak Isospin Violations in Charged and Neutral Higgs Couplings from SUSY Loop Corrections

, 2003
Supersymmetric QCD and supersymmetric electroweak loop corrections to the violations of weak isospin to Yukawa couplings are investigated. Specifically it involves an analysis of the supersymmetric loop corrections to the Higgs couplings to the third ...

Phase Structure of Nambu-Jona-Lasinio Model at Finite Isospin Density

, 2005
In the frame of flavor SU(2) Nambu--Jona-Lasinio model with $U_A(1)$ breaking term we found that, the structure of two chiral phase transition lines does not exist at low isospin density in real world, and the critical isospin chemical potential for pion

Isospin symmetry breaking [PDF]

Proceedings of 6th International Workshop on Chiral Dynamics — PoS(CD09), 2010
We discuss the separation of isospin-symmetric and isospin-breaking contributions in the hadronic observables within the framework of QCD plus QED. Further, we briefly review some recent work on the low-energy hadron phenomenology, in which the isospin-breaking effect plays a prominent role.

Isospin mixing in the vicinity of the N=Z line

, 2010
We present the isospin- and angular-momentum-projected nuclear density functional theory (DFT) and its applications to the isospin-breaking corrections to the superallowed beta-decay rates in the vicinity of the N=Z line. A preliminary value obtained for
