Constraints on the coupling with photons of heavy axion-like-particles from Globular Clusters / Carenza, Pierluca (Bari U. ; INFN, Bari) ; Straniero, Oscar (Rome Observ.) ; Döbrich, Babette (CERN) ; Giannotti, Maurizio (Barry U.) ; Lucente, Giuseppe (Bari U.) ; Mirizzi, Alessandro (Bari U. ; INFN, Bari)
We update the globular cluster bound on massive ($m_a$ up to a few 100 keV) axion-like particles (ALP) interacting with photons. The production of such particles in the stellar core is dominated by the Primakoff $\gamma + Ze\to Ze +a$ and by the photon coalescence process $\gamma+\gamma\to a$. [...]

Flavour-dependent radiative correction to neutrino-neutrino refraction / Mirizzi, Alessandro (Munich, Max Planck Inst.) ; Pozzorini, Stefano (CERN) ; Raffelt, Georg G. (Munich, Max Planck Inst.) ; Serpico, Pasquale D. (CERN)
In the framework of the Standard Model we calculate the flavour non-universal correction for neutrino refraction in a neutrino background and verify a similar previous result for the case of ordinary-matter background. The dominant term arises at loop level and involves tau leptons circulating in the loop. [...]

Collective flavor transitions of supernova neutrinos / Sigl, Gunter (Hamburg U., Inst. Theor. Phys. II) ; Tomas, Ricard (Hamburg U., Inst. Theor. Phys. II) ; Esteban-Pretel, Andreu (Valencia U.) ; Pastor, Sergio (Valencia U.) ; Mirizzi, Alessandro (Munich, Max Planck Inst.) ; Raffelt, Georg G. (Munich, Max Planck Inst.) ; Serpico, Pasquale D. (CERN)
We give a very brief overview of collective effects in neutrino oscillations in core collapse supernovae where refractive effects of neutrinos on themselves can considerably modify flavor oscillations, with possible repercussions for future supernova neutrino detection. We discuss synchronized and bipolar oscillations, the role of energy and angular neutrino modes, as well as three-flavor effects. [...]

Nonstandard neutrino-neutrino refractive effects in dense neutrino gases / Blennow, Mattias (Munich, Max Planck Inst.) ; Mirizzi, Alessandro (Munich, Max Planck Inst.) ; Serpico, Pasquale D. (CERN ; Fermilab)
We investigate the effects of nonstandard four-fermion neutrino-neutrino interactions on the flavor evolution of dense neutrino gases. We find that in the regions where the neutrino-neutrino refractive index leads to collective flavor oscillations, the presence of new neutrino interactions can produce flavor equilibration in both normal and inverted neutrino mass hierarchy.
