The spin–triplet states of charmonium (S1(J/ψ, ψ ), PJ(χc0,c1,c2)) have been extensively studied by SLAC, Fermilab, and BES during the last 30 years. The spin–singlet states have largely defied identification and study. Neither η c2 S0), nor hc(1 P1), nor ηb(1 S0) have ever been convincingly identified. This leaves us largely in the dark about the character of the all–important spin–spin hyperf...

The singlet and triplet differential cross sections for pp → ppπ • have been estimated for the first time at 325, 350, 375 and 400 MeV using the results of the recent experimental measurements [Phys. Rev. C 63, 064002 (2001)] of Meyer et al.

— We consider the three basic seesaw scenarios (with fermionic singlets, scalar triplets or fermionic triplets) and discuss their phenomenology, aside from neutrino masses. We use the effective field theory approach and compare the dimension-six operators characteristic of these models. We discuss the possibility of having large dimension-six operators and small dimension-five (small neutrino m...

The simplest little Higgs model based on a gauge group SU(3)color×SU(3)weak× U(1)X contains three vector-like lepton singlets with electric charge 0 below electroweak energy scale. They are counter partners of the first component in the leptonic triplet of SU(3)L for each generation. Due to Yukawa couplings the neutral singlets not only have a Dirac mass, but also couple to the neutrinos. Thus ...

We perform an analysis of the Renormalization Group evolution of the couplings in an extension to the Standard Model which contains a real triplet in the Higgs sector. Insisting that the model remain valid up to 1 TeV allow us to map out the region of allowed mass for the Higgs bosons. We conclude that it is possible for there to be no light Higgs bosons without any otherwise dramatic deviation...

We construct a supersymmetric version of the triplet Higgs model for neutrino masses, which can generate a baryon asymmetry of the Universe through leptonnumber violation and is consistent with the gravitino constraints.

In this paper, we first present a new concept of 'weight' for 64 triplets and define a different weight for each kind of triplet. Then, we give a novel 2D graphical representation for DNA sequences, which can transform a DNA sequence into a plot set to facilitate quantitative comparisons of DNA sequences. Thereafter, associating with a newly designed measure of similarity, we introduce a novel ...

Assuming equal tree-level Majorana masses for the standard-model neutrinos, either from the canonical seesaw mechanism or from a heavy scalar triplet, I discuss how their radiative splitting may be relevant to neutrinoless double beta decay and neutrino oscillations. • Talk given at the International Conference on Non-Accelerator New Physics, Dubna, Russia (June 28 July 3, 1999).
