“…where summation over i, j = e, µ, τ is implied, we have allowed for the possibility of X-induced neutrino flavor-change, and P L,R = 1 2 (1 ∓ γ 5 ). Since presently there is still no compelling evidence for the existence of predominantly right-handed neutrinos [17], we have neglected their potential couplings to X. We also have not included terms involving the muon or tau, as the electron is the only charged lepton taking part in the reactions we will study.…”

We consider nonstandard interactions of neutrinos with electrons arising from a new light spin-1 particle with mass of tens of GeV or lower and couplings to the neutrinos and electron. This boson is not necessarily a gauge boson and is assumed to have no mixing with standard-model gauge bosons. Adopting a model-independent approach, we study constraints on the flavor-conserving and -violating couplings of the boson with the leptons from a number of experimental data. Specifically, we take into account the (anti)neutrino-electron scattering and e + e − → ννγ measurements and keep explicitly the dependence on the new particle mass in all calculations. We find that one of the two sets of data can provide the stronger constraints, depending on the mass and width of the boson. Also, we evaluate complementary constraints on its separate flavor-conserving couplings to the electron and neutrinos from other latest experimental results.

“…Very exciting discoveries regarding neutrino masses have recently been made with solar neutrinos, in particular by the Sudbury Neutrino Observatory (SNO). Solar neutrinos 15 The second number in each bracket gives the fraction of the total solar ν flux. Energy spectra of the ν e fluxes from the various sources and rates for the various detection reactions have been predicted in the framework of the Standard Solar Model (SSM) 16,17 .…”

“…For each event (electron) the effective kinetic energy T, the angle Θ sun with respect to the direction from the sun, and the distance (radius) R from the detector center were measured. The principle of the analysis goes as follows: The three measured distributions N (x) meas of x = T, Θ sun , R 3 from 2928 events with 5 < T < 20 MeV can be fitted by three linear combinations (15) where w i (x) are characteristic probability density functions known from Monte Carlo simulations (e.g. w ES (cos Θ sun ) is strongly peaked in the direction from the sun, i.e.…”

The recent observation of neutrino oscillations with atmospheric and solar neutrinos, implying that neutrinos are not massless, is a discovery of paramount importance for particle physics and particle astrophysics. This invited lecture discusses -hopefully in a way understandable also for the non-expert -the physics background and the results mainly from the two most relevant experiments, SuperKamiokande and SNO. It also addresses the implications for possible neutrino mass spectra. We restrict the discussion to three neutrino flavours (νe, νµ, ντ ), not mentioning a possible sterile neutrino.

The ref(2)P gene of Drosophila melanogaster is implicated in sigma rhabdovirus multiplication. A permissive allele was cloned and sequenced. The structural gene (3.1 kbp) is divided into three exons. The mRNAs are heterogeneous in size. They differ only in the 5′ end of the first exon. The sequence upstream of the short mRNAs contains classical promoter elements. No TATA and CAAT boxes are appropriately positioned upstream of the initiation sites of the long mRNAs, but several repeats, palindromic sequences and inverted CAAT boxes are present. These observations, together with the tissue‐dependent distribution of short and long transcripts, support the hypothesis of the existence of at least two classes of genuine initiation sites. The long size of the untranslated leader RNA region suggests a control of gene expression at the translation level. The same translation product of 599 amino acids (76.3 kd) is predicted for all mRNAs, but the in vitro translation product migrates in SDS‐PAGE with a higher apparent mol. wt (115‐125 kd). The putative ref(2)P protein contains internal repeats, PEST regions which may be signals for protein degradation, and interesting structural motifs such as zinc finger and amphiphilic helices. These later motifs could be mitochondrial pre‐sequences. The degeneration of mitochondria is observed in the spermatids of sterile male flies homozygous for the loss‐of‐function alleles. The amino acid sequence of the ref(2)P product shows no homology with any known protein from the data banks.
