Some potential problems of OHe composite dark matter
Jean-René Cudell, Maxim Khlopov, Quentin Wallemacq
Among composite-dark-matter scenarios, one of the simplest and most predictive is that of O-helium (OHe) dark atoms, in which a lepton-like doubly charged particle O is bound with…
Dynamical flavor origin of symmetries
D. Aristizabal Sierra, Mikael Dhen, Chee Sheng Fong +1
Discrete Abelian symmetries () are a common "artifact" of beyond the standard model physics models. They provide different avenues for constructing consistent scenari…
Search for magnetic fields in particle-accelerating colliding-wind binaries
C. Neiner, J. Grunhut, B. Leroy +2
Some colliding-wind massive binaries, called particle-accelerating colliding-wind binaries (PACWB), exhibit synchrotron radio emission, which is assumed to be generated by a stella…
Weighted principal component analysis: a weighted covariance eigendecomposition approach
Ludovic Delchambre
We present a new straightforward principal component analysis (PCA) method based on the diagonalization of the weighted variance-covariance matrix through two spectral decompositio…
Control of molecular dynamics with zero-area fields: Application to molecular orientation and photofragmentation
D. Sugny, Stéphane Vranckx, Mamadou Ndong +3
The constraint of time-integrated zero-area on the laser field is a fundamental, both theoretical and experimental requirement in the control of molecular dynamics. By using techni…
Dual parametrization of generalized parton distributions in two equivalent representations
Dieter Müller, Maxim V. Polyakov, Kirill M. Semenov-Tian-Shansky
The dual parametrization and the Mellin-Barnes integral approach represent two frameworks for handling the double partial wave expansion of generalized parton distributions (GPDs)…
