Lepton-flavour violation in hadronic tau decays and - conversion in nuclei

Tomáš Husek, Kevin Monsálvez-Pozo, Jorge Portolés

Within the Standard Model Effective Field Theory framework, with operators up to dimension 6, we perform a model-independent analysis of the lepton-flavour-violating processes invo…

Radiative corrections for the decay

Tomáš Husek

Electromagnetic form factors serve to explore the intrinsic structure of nucleons and their strangeness partners. For the decay , due to limited phase space, the eff…

The Explosion Mechanism of Core-Collapse Supernovae and Its Observational Signatures

Ondřej Pejcha

The death of massive stars is shrouded in many mysteries. One of them is the mechanism that overturns the collapse of the degenerate iron core into an explosion, a process that det…

Does a pristine, unreconstructed SrTiO(001) surface exist?

Igor Sokolović, Giada Franceschi, Zhichang Wang +6

The surfaces of perovskite oxides affect their functional properties, and while a bulk-truncated (11) termination is generally assumed, its existence and stability is contr…

Spin Change of Asteroid 2012 TC4 probably by Radiation Torques

Hee-Jae Lee, Josef Ďurech, David Vokrouhlický +9

Asteroid 2012 TC4 is a small (10 m) near-Earth object that was observed during its Earth close approaches in 2012 and 2017. Earlier analyses of light curves revealed its exci…

The Lifetimes of Star Clusters Born with a Top-heavy IMF

Hosein Haghi, Ghasem Safaei, Akram Hasani Zonoozi +1

Several observational and theoretical indications suggest that the initial mass function (IMF) becomes increasingly top-heavy (i.e., overabundant in high-mass stars with mass $m >…

Temperature field and heat generation at the tip of a cutout in a viscoelastic solid body undergoing loading

Vít Průša, Karel Tůma

Using the finite element method we quantitatively analyse temperature field evolution in a viscoelastic solid undergoing a loading--unloading process. In particular we investigate…
