The seesaw path to leptonic CP violation
European Physical Journal C: Particles and Fields, 2017 Future experiments such as SHiP and high-intensity $$e^+ e^-$$ e + e - colliders will have a superb sensitivity to heavy Majorana neutrinos with masses below $$M_Z$$ M Z .

, 2004 Soft supersymmetry breaking terms involving heavy singlet sneutrinos provide new sources of lepton number violation and of CP violation. In addition to the CP violation in mixing, investigated previously, we find that `soft leptogenesis' can be generated

Biodiversity–food trade‐offs when agricultural land is spared from production
American Journal of Agricultural Economics, EarlyView.Abstract Biodiversity conservation in agricultural landscapes, the world's predominant land use, could involve sparing, or setting aside, agricultural land from production, implying biodiversity–food trade‐offs. Employing bird species and agricultural data in two panel data sets, we evaluate the extent of set‐aside's trade‐offs in England between 1992 ...

, 2002 In these lecture notes an introduction is given to some ideas and attempts to understand the origin of the matter-antimatter asymmetry of the universe. After the discussion of some basic issues of cosmology and particle theory the scenarios of electroweak baryogenesis, GUT baryogenesis, and leptogenesis are outlined.

B PHYSICS AND CP VIOLATION [PDF]
Fundamental Interactions, 2004 These lectures provide a basic overview of topics related to the study of CP Violation in B decays. In the first lecture, I review the basics of discrete symmetries in field theories, the quantum mechanics of neutral but flavor-non-trivial mesons, and the classification of three types of CP violation.

Affirmative action without competition
American Journal of Political Science, EarlyView.Abstract Affirmative action is standardly pursued in relation to admissions to prestigious universities, in hiring for prestigious jobs, and when it comes to being elected to parliament. Central to these forms of affirmative action is that they have to do with competitive goods.

Resonant CP violation in rare τ ± decays
Journal of High Energy Physics, 2017 In this work, we study the lepton number violating tau decays via intermediate on-shell Majorana neutrinos N j into two scalar mesons and a lepton τ ± → M 1 ± N j → M 1 ± M 2 ± ℓ ∓. We calculate the Branching ratios Br(τ ±) and the CP asymmetry (Γ(τ +) −

When you come at the king: Opposition coalitions and nearly stunning elections
American Journal of Political Science, EarlyView.Abstract Opposition coalitions under electoral authoritarianism have been associated with greater likelihood of opposition victory and democratization. I argue, however, that coalitions also entail significant downside risks with implications for longer term prospects for democracy.

A sparse latent class model incorporating response times
British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Diagnostic models (DM) have been widely used to classify respondents' latent attributes in cognitive and non‐cognitive assessments. The integration of response times (RTs) with DM presents additional evidence to understand respondents' problem‐solving behaviours.
