Exploring Dark Photon Production and Kinetic Mixing Constraints in Heavy‐Ion Collisions
Astronomische Nachrichten, EarlyView.ABSTRACT Vector U‐bosons, often referred to as “dark photons,” are potential candidates for mediating dark matter interactions. In this study, we outline a procedure to derive theoretical constraints on the upper bound of the kinetic mixing parameter ϵ2MU$$ {\upvarepsilon}^2\left({M}_U\right) $$ using dilepton data from heavy‐ion from SIS to RHIC ...

Le vote blanc et nul en Wallonie : analyse écologique et individuelle
Belgeo, 2010 Blank and null votes are probably the electoral behaviour least taken into account by electoral studies. Though, in a democracy like Belgium, these votes are far from negligible and offer an untypical geography which underlines border areas.

Pion correlations in Nuclear Matter [PDF]
Int.J.Mod.Phys.E20:63-80,2011, 2009 The saturation properties of the nuclear matter taking pion correlations into account is studied. We construct a Bogoliubov transformations for the pion pair operators and calculate the energy associated with the pion pairs. The pion dispersion relation is investigated. We next study the correlation energy due to one pion exchange in nuclear matter and

Coupled channels calculation of a pion-Lambda-nucleon quasibound state
, 2010 We extend the study of a JP=2+, I=3/2 pion-Lambda-nucleon quasibound state [Phys. Rev. D 78, 014013 (2008)] by solving nonrelativistic Faddeev equations, using 3S1-3D1, Lambda N - Sigma N coupled channels Chiral Quark Model local interactions, and pion ...

Physics Letters B, 2010 The residual mass of the pion in a finite spatial box at vanishing quark masses, the mass gap, is computed with two flavors of dynamical clover fermions. The result is compared with predictions of chiral perturbation theory in the delta regime.

Pion Compton scattering and bremsstrahlung
, 2008 The pion-polarizability functions are structure functions of pion-Compton scattering. They can be assessed in high-energy pion-nucleus bremsstrahlung reactions, $\pi^- +A\to\pi^- +\gamma +A$.

Twist-2 Light-Cone Pion Wave Function [PDF]
, 1997 We present an analysis of the existing constraints for the twist-2 light-cone pion wave function. We find that existing information on the pion wave function does not exclude the possibility that the pion wave function attains its asymptotic form.

International Journal of Modern Physics E, 2011 We revisit the problem of a mechanism that generates the mass spectrum of elementary particles. This has vexed physicists for several decades now. In this connection, we deduce a formula that gives the masses of all known elementary particles, even though other quantum numbers are suppressed.
