Pion-pion scattering in two dimensions [PDF]
Physical Review D, 1999 Massive two-flavor QED_2 is known to have many similarities to the two-flavor QCD_4. Here we compare the - scattering amplitudes (actually an analog process in QED_2) of the two theories. The QED_2 amplitude is computed from the bosonized version of the model while the QCD_4 amplitude is computed from an effective low energy chiral Lagrangian.

L'abstentionnisme électoral en Belgique : données individuelles et agrégées à Charleroi
L'Espace Politique, 2011 Electoral absenteeism is a common studied subject in the Anglo-Saxon and French scientific world. But researches about it in Belgium, where voting is compulsory are not far from being null.

New class of compact stars: Pion stars [PDF]
Physical Review D, 2018 We investigate the viability of a new type of compact star whose main constituent is a Bose-Einstein condensate of charged pions. Several different setups are considered, where a gas of charged leptons and neutrinos is also present.

Pion Production in Pion Nucleon Scattering and Pion-Pion Interaction [PDF]
Progress of Theoretical Physics, 1962 The reaction pi + N yields 2 pi + N is discussed. The production process is assumed to take place mainly via pi - pi interactions, which are studied using an extrapolation formula (G. F. Chew and F. E. Low, Phys. Rev., 113: 1640 (1959)). A program giving a consistent explanation to the process at 0.3 to 1.5 Bev is presented.

Transverse‐Electric Cherenkov Radiation for TeV‐Scale Particle Detection
Advanced Science, EarlyView.Finite refractive indices of naturally existing materials place a fundamental ceiling on the momentum of detectable particles in traditional Cherenkov detectors. This work demonstrates transverse‐electric graphene plasmon Cherenkov radiation, breaking the momentum barrier for particle detection beyond the TeV scale with exceptional robustness and ...

Proton and pion distribution functions in counterpoint
Physics Letters B, 2022 Working with proton and pion valence distribution functions (DFs) determined consistently at the same, unique hadron scale and exploiting the possibility that there is an effective charge which defines an evolution scheme for DFs that is all-orders exact,

physica status solidi (b), EarlyView.An electron polaron in bismuth ferrite needs to overcome an energy barrier to hop from initial iron site Fe1 to final iron site Fe2. Here, this energy barrier was determined ab initio for hops in perfect bismuth ferrite and at neutral ferroelectric domain walls.

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.

Dynamics of Purification in Cu2O
physica status solidi (b), EarlyView.Rydberg excitons in Cu2O have been shown to be highly efficient in neutralizing and screening charged impurities, which is referred to as purification. In this manuscript, the dynamics of the purification process are investigated under varying probe exciton‐ and plasma density. The transient absorption of Rydberg excitons is analyzed and five different
