Flavored quantum Boltzmann equations
We derive from first principles, using nonequilibrium field theory, the quantum Boltzmann equations that describe the dynamics of flavor oscillations, collisions, and a time-dependent mass matrix in the early universe. Working to leading nontrivial order in ratios of relevant time scales, we study in detail a toy model for weak-scale baryogenesis: two scalar species that mix through a slowly va...
متن کاملPurely Flavored Leptogenesis
We study a model for leptogenesis in which the total CP asymmetries in the decays and scatterings involving the SU(2) singlet seesaw neutrinos Nα vanish (ǫNα = 0). Leptogenesis is possible due to non-vanishing CP violating lepton flavor asymmetries, realizing a situation in which the baryon asymmetry is due exclusively to flavor effects. We study the production of a net lepton asymmetry by solv...
متن کاملA pilot study of preschoolers' use of regular-flavored dentifrices and those flavored for children.
Ingestion of fluoride dentifrice by preschool children recently has been implicated as a risk factor for dental fluorosis. The availability of dentifrices flavored for children could increase fluoride ingestion by young children at risk for dental fluorosis. This article reports results of a pilot study of use of regular-flavored dentifrice and those flavored for children among 29 preschool chi...
متن کاملOdd-flavored QCD3 and Random Matrix Theory
We consider QCD3 with an odd number of flavors in the mesoscopic scaling region where the field theory finite-volume partition function is equivalent to a random matrix theory partition function. We argue that the theory is parity invariant at the classical level if an odd number of masses are zero. By introducing so-called pseudo-orthogonal polynomials we are able to relate the kernel to the k...
متن کاملCharged Higgs production in the flavored MSSM
In the Minimal Supersymmetric Standard Model squark mixing can significantly change the pattern of charged-Higgs production. We find that non-minimal flavor structures can have a sizeable impact on the charged-Higgs production cross section, whereas charged-Higgs searches may be able to probe flavor structures not accessible to rare kaon, bottom or charm experiments, and can invalidate the assu...
