“…The GUT's and SUSY offer a variety of mechanisms which allow the 0νββ-decay to occur [5]. The best known possibility is via the exchange of a Majorana neutrino between the two decaying neutrons [1][2][3][4]6], but increased attention is paid to more exotic processes, like the supersymmetric R-parity violating mechanisms of 0νββ-decay [7][8][9][10][11][12]. Recent review articles [13,14] give a detailed account of the latest developments in this field.…”

We have examined the importance of momentum dependent induced nucleon currents such as weak-magnetism and pseudoscalar couplings to the amplitude of neutrinoless double beta decay (0νββ-decay) in the mechanisms of light and heavy Majorana neutrino as well as in that of Majoron emission.Such effects are expected to occur in all nuclear models in the direction of reducing the light neutrino matrix elements by about 30%. To test this we have performed a calculation of the nuclear matrix elements of the experimentally interesting nuclei A = 76, 82, 96, 100, 116, 128, 130, 136 and 150 within the proton-neutron renormalized Quasiparticle Random Phase Approximation (pn-RQRPA). We have found that indeed such corrections vary * Permanent address:

“…In the previous studies such estimates were performed in the framework of / RMSSM with supergravity mediated SUSY breaking by means of GUT constraints [17,19] or additional assumptions relating sfermions and gauginos masses [15,16]. We will show that one can find quantitatively new constraints [18] within GMSB models.…”

“…Above features make / RMSSM models appropriate for the description of 0νββ. Because this process is known to be very sensitive to supersymmetric and R-parity breaking parameters, data from the nowadays double beta experiments allow to establish stringent limits on / RMSSM physics [15,16,17,18,19,20,21,25].…”

“…The formulae (17) and (18) may therefore serve as boundary conditions for evolution of soft parameters at the electroweak scale. Our procedure resulting in low energy spectrum of SUGRA and GMSB MSSM models and its application to the description of 0νββ decay can be found in our previous papers [18,19], so here we only sketch its most important features.…”

The Minimal Supersymmetric Standard Model with gauge mediated supersymmetry breaking and trilinear R-parity violation is applied to the description of neutrinoless double beta decay. A detailed study of limits on the parameter space coming from the B → Xsγ processes by using the recent CLEO results is performed. The importance of two-nucleon and pion-exchange realizations of 0νββ decay together with gluino and neutralino contributions to this process are addressed. We have deduced new limits on the trilinear R-parity breaking parameter λ ′ 111 from the non-observability of 0νββ in several medium and heavy open-shell nuclei for different gauge mediated breaking scenarios. In general, they are stronger than those known from other analyses. Also some studies with respect to the future 0νββ projects are presented.

“…As one can see from Eqs. (5)- (8) in Ref. 11, those individual limits give rise to some constraints on the products of R p violating couplings such as λ 11i λ 1i1 and ∆ n λ k11 λ nkj .…”

NEW CONSTRAINTS ON R_p VIOLATING COUPLINGS VIA SUSY ACCOMPANIED NEUTRINO EXCHANGE MECHANISM OF NEUTRINOLESS DOUBLE BETA DECAY

We consider ββ 0ν decay induced by light Majorana neutrino exchange between decaying nucleons, accompanied by, in particular, the slepton exchange inside a nucleon. This contribution to ββ 0ν is generated from the Rp violating terms and the mixing of the standard light neutrinos with neutral heavy particles or light sterile neutrinos. To determine the unknown mixing factor ∆, we take into account the four-neutrino model with three ordinary neutrinos and one sterile neutrino. Imposing the current experimental lower half-life limit, a set of constraints on λ 311 λ 123 and λ 311 λ 133 is obtained. Comparing with the limits on the products of the individual bounds on λ and λ , we find that the former is stronger while the latter is weaker. 2039 Mod. Phys. Lett. A 1998.13:2039-2044.
