Nucleosynthesis in Supernovae [PDF]
Physical Review Letters, 1999 Core collapse supernovae are dominated by energy transport from neutrinos. Therefore, some supernova properties could depend on symetries and features of the standard model weak interactions. The cross section for neutrino capture is larger than that for

Explosive Nucleosynthesis: Prospects [PDF]
Physics Reports, 1999 Explosive nucleosynthesis is a combination of the nuclear physics of thermonuclear reactions, and the hydrodynamics of the plasma in which the reactions occur. It depends upon the initial conditions---the stellar evolution up to the explosive instability,

Leptonic Photons and Nucleosynthesis [PDF]
Physics Letters B, 1996 Should $U(1)$ long-range forces be associated to electron, muon and/or tau quantum number then their ''fine structure constants" are seen to be bound by nucleosynthesis data to be less than about $1.7 \times 10^{-11}$.

Neutrinos and Primordial Nucleosynthesis [PDF]
Nuclear Physics B - Proceedings Supplements, 2004 The importance of the Big Bang Nucleosynthesis (BBN) as a unique tool for studying neutrino properties is discussed, and the recent steps towards a self-consistent and robust handling of the weak reaction decoupling from the thermal bath as well as of ...

Neutrino Effects in Nucleosynthesis [PDF]
Neutrino Physics, 2000 The nucleosynthesis within a Type II supernova occurs in an intense neutrino flux. I discuss some of the effects associated with neutrino interactions, including direct synthesis in the neutrino process, the role of neutrinos in controlling the r-process

Neutrino nucleosynthesis [PDF]
Physics Letters B, 2005 We study neutrino process nucleosynthesis in massive stars using newly calculated cross sections, an expanded reaction network, and complete and self-consistent models of the progenitor star. We reevaluate the production of light isotopes from abundant progenitors as well as that of rare, heavy, proton-rich isotopes.

Hypernovae and their nucleosynthesis [PDF]
Symposium - International Astronomical Union, 2003 We review the characteristics of nucleosynthesis in ‘hypernovae’, i.e., core-collapse supernovae with very large explosion energies (≳ 1052 ergs). The hypernova yields show the following characteristics: (i) the mass ratio between the complete and incomplete Si burning regions is larger in hypernovae than normal supernovae.

Hydrogen Tunneling in Stoichiometric and Catalytic Reactions involving Transition Metals
ChemCatChem, Volume 15, Issue 24, December 19, 2023., 2023 An overview on the importance of the participation of hydrogen tunneling in E−H bond activation reactions (E=C, O, Si…) mediated by transition metals is presented. Understanding when hydrogen tunneling occurs can be a powerful tool for designing new catalysts to perform challenging reactions.

Annalen der Physik, Volume 535, Issue 12, December 2023., 2023 This article describes the implementation of low‐frequency axion haloscope setups inside the future BabyIAXO magnet. The RADES proposal has a potential sensitivity to the axion‐photon coupling down to values corresponding to the KSVZ model, in the mass range between 1 and 2 μ$\umu$eV.
