Phenomenological constraints on broken R parity symmetry in supersymmetry models

M Chemtob - Progress in Particle and Nuclear Physics, 2005 - Elsevier
The R parity odd renormalizable Yukawa interactions of quarks and leptons with scalar
superpartners have the ability to violate the baryon and lepton numbers, change the hadron …

Effects of supergravity-induced electroweak breaking on rare b-decays and mixings

S Bertolini, F Borzumati, A Masiero, G Ridolfi - Nuclear Physics B, 1991 - Elsevier
We perform a complete computation of the contributions to b→ s+ γ, b→ s/+/−, b→ s ν ν, b→
s+ g, B do− B do and B so− B so in minimal spontaneously broken N= 1 supergravity with …

Supersymmetry and neutrinoless double β decay

M Hirsch, HV Klapdor-Kleingrothaus, SG Kovalenko - Physical Review D, 1996 - APS
Neutrinoless double β decay (0νββ) induced by superparticle exchange is investigated.
Such a supersymmetric (SUSY) mechanism of 0νββ decay arises within SUSY theories with …

Top searches and R-parity violation at hardon colliders

H Dreiner, RJN Phillips - Nuclear Physics B, 1991 - Elsevier
In R p-violating supersymmetric theories there are new two-body top quark decays which
can substantially suppress the branching fraction of the Standard Model process t→ bW+→ …

Supersymmetry without R parity and without lepton number

T Banks, Y Grossman, E Nardi, Y Nir - Physical Review D, 1995 - APS
We investigate supersymmetric models where neither R parity nor lepton number is
imposed. Neutrino masses can be kept highly suppressed compared to the electroweak …

Some implications of a supersymmetric model with -parity-breaking bilinear interactions

S Roy, B Mukhopadhyaya - Physical Review D, 1997 - APS
We investigate a supersymmetric scenario where R parity is explicitly broken through a term
bilinear in the lepton and Higgs superfields in the superpotential. We show that kee** …

Neutrino masses in supersymmetry with spontaneously broken R-parity

JC Romao, JWF Valle - Nuclear Physics B, 1992 - Elsevier
The neutrino mass spectrum that arises in supersymmetry models with spontaneously
broken R-parity is studied in detail. We analyse the attainable values for m ν e, m ν μ and m …

Supersymmetric neutrino masses, R-symmetries, and the generalized μ-problem

HP Nilles, N Polonsky - Nuclear Physics B, 1997 - Elsevier
In supersymmetric models a tree-level neutrino mass could originate from the (weak-scale)
superpotential. We propose and examine a realization of that idea, which arises naturally in …

Gauge theories and the physics of neutrino mass

JWF Valle - Particle and Nuclear Physics, 1991 - Elsevier
The basic physics of neutrino mass is reviewed from a gauge theoretic point of view. Various
extensions of the standard electroweak theory are considered, along with their implications …
