Beware of CaBER: Filament thinning rheometry does not always give `the' relaxation time of polymer solutions

Autor: Gaillard, Antoine, Gutierrez, Miguel Angel Herrada, Deblais, Antoine, Eggers, Jens, Bonn, Daniel

The viscoelastic relaxation time of a polymer solution is often measured using Capillary Breakup Extensional Rheometry (CaBER) where a droplet is placed between two plates which are pulled apart to form a thinning filament. For a slow plate retractio

Monochromatic neutrinos from dark matter through the Higgs portal

Autor: de la Torre, Pablo, Gutiérrez, Miguel, Masip, Manuel

We define a minimal model of dark matter with a fermion singlet $\chi$ coupled to the visible sector through the Higgs portal and with a heavy Dirac neutrino $N$ that opens the annihilation channel $\chi \chi \to N \nu$. The model provides the observ

High energy cosmic rays "illuminate" the Sun and produce an image that could be observed in up to five different channels: a cosmic ray shadow (whose energy dependence has been studied by HAWC); a gamma ray flux (observed at $E\le 200$ GeV by Fermi-L
