Flavoured leptogenesis in the CTP formalism

Flavoured Soft Leptogenesis

We study the impact of flavour in “soft leptogenesis” (leptogenesis induced by soft supersymmetry breaking terms). We address the question of how flavour effects can affect the region of parameters in which successful soft leptogenesis induced by CP violation in the right-handed sneutrino mixing is possible. We find that for decays which occur in the intermediate to strong washout regimes for a...

CTP: A New Constraint-Based Formalism for Conditional, Temporal Planning

Pesto Flavoured Security

We demonstrate that symmetric-key cryptography can be used for both read and write access control. One-time write access can be granted by handing over an encryption key, and our encryption framework allows the revocation of previously granted rights. The number of keys to be managed explicitly grows linearly with the number of access control policies a user defines, making security manageable....

Lifetimes of b-flavoured hadrons

I discuss the heavy quark expansion for the inclusive widths of heavy-light hadrons, which predicts quite well the experimental ratios of Bq meson lifetimes. As for Λb, current determinations of O(m−3 b ) contribution to τ(Λb) do not allow to explain the small measured value of τ(Λb)/τ(Bd). As a final topic, I discuss the implications of the measurement of the Bc lifetime. 1. Lifetimes of heavy...

Flavoured aspects of the QCD thermodynamics

We discuss recent progress in lattice QCD studies on various aspects involving strange and heavy quarks. Appropriate combinations of conserved net strange and net charm fluctuations and their correlations with other conserved charges provide evidence that in the hadronic phase so far unobserved hadrons contribute to the thermodynamics and need to be included in hadron resonance gas models. In t...
