A possible origin of the q=4/3 diquark
Alejandro Rivero
Between the new physics candidates proposed to explain the asymmetry measured in the Tevatron, there are some scalar diquarks with electric charge +4/3. This kind of diq…
A new Koide tuple: strange-charm-bottom
Alejandro Rivero
With the negative sign for , the quarks strange, charm and bottom make a Koide tuple. It continues the c-b-t tuple previously found by Rodejohann and Zhang and, more pec…
Unbroken supersymmetry without new particles
Alejandro Rivero
We consider Koide's equation for charged leptons jointly with hypotheses implied in the ancient Dual Quark-Gluon model. The focus is to motivate the possibility of a supersymmetric…
Third Spectroscopy with a hint of superstrings
A. Rivero
New regularities found in the pseudoscalar meson octet are reported. They invite to reconsider models where elementary fermions and composite QCD open strings can be grouped in com…
Mass terms to break susy-like degeneration
Alejandro Rivero
We suggest a very simple but general operator to break mass degeneration between representations of the Poincare group having spin 1 and 1/2. A quantity very similar, at experiment…
Regularities in electromagnetic decay widths
Alejandro Rivero
We revisit Sakurai's remark on the regularities of lepton-pair widths for mesons, extending the panorama to radiative and total decays. The regularities persist, and som…
Supersymmetry with composite bosons
Alejandro Rivero
We note that hadronic susy (empirical quark-diquark) symmetry can be expanded into the lepton sector, and that for three generations the counting of degrees of freedom is the one w…
GUT angle minimises decay
Alejandro Rivero
The GUT value of Weinberg's angle is also the value that minimises the total square matrix elements of decay, independently of any GUT consideration, and thus the one that ma…
Anomaly-driven decay of massive vector bosons
Alejandro Rivero
We inquire if the total decay rate of neutral vector mesons can contain relevant off-shell contributions from the triangle anomaly. The answer seems to be affirmative for the case…
The strange formula of Dr. Koide
Alejandro Rivero, Andre Gsponer
We present a short historical and bibliographical review of the lepton mass formula of Yoshio Koide, as well as some speculations on its extensions to quark and neutrino masses, an…
Evidence for radiative generation of lepton masses
Hans de Vries, Alejandro Rivero
We present a fit to the experimental charged lepton masses as coming from radiative corrections in QED.
The 115 GeV signal from nuclear physics
Alejandro Rivero
According standard models of nuclei, steepest variations of binding energy at the drip lines should happen for nuclear masses of 45, 68, 92, 115, 175 and 246 GeV. We explore the co…
