Jack superpolynomials: physical and combinatorial definitions
Patrick Desrosiers, Luc Lapointe, Pierre Mathieu
Jack superpolynomials are eigenfunctions of the supersymmetric extension of the quantum trigonometric Calogero-Moser-Sutherland. They are orthogonal with respect to the scalar prod…
On the electromagnetic form factors of the proton from generalized Skyrme models
Jimmy Fortier, Luc Marleau
We compare the prediction of Skyrme-like effective Lagrangians with data for electromagnetic form factors of proton and consider the possibility of fixing the parameters of these h…
The Equilibrium Structure of CDM Halos
Paul R. Shapiro, Ilian T. Iliev, Hugo Martel +2
Dark-matter halos are the scaffolding around which galaxies and clusters are built. They form when the gravitational instability of primordial density fluctuations causes regions w…
A Period and a Prediction for the Of?p Spectrum Alternator HD 191612
Nolan R. Walborn, Ian D. Howarth, Gregor Rauw +7
The observational picture of the enigmatic O-type spectrum variable HD191612 has been sharpened substantially. A symmetrical, low-amplitude light curve with a period near 540 d has…
Alternative Perspective on Quantum Tunneling and Instantons
F. Paradis, H. Kroger, G. Melkonyan +1
We present a new way to compute and interpret quantum tunneling in a 1-D double-well potential. For large transition time we show that the quantum action functional gives an analyt…
Low x saturation at HERA ?
J. R. Forshaw, R. Sandapen, G. Shaw
We compare the predictions of two distinct dipole models for inclusive and exclusive diffractive processes. While only one of these dipole models contains perturbative saturation d…
