Theoretical and phenomenological implications of R-parity violation in supersymmetric theories are discussed in the context of particle physics and cosmology. Fundamental aspects include the relation with continuous and discrete symmetries and the various allowed patterns of R-parity breaking. Recent developments on the generation of neutrino masses and mixings within different scenarios of R-parity violation are discussed. The possible contribution of Rparity-violating Yukawa couplings in processes involving virtual supersymmetric particles and the resulting constraints are reviewed. Finally, direct production of supersymmetric particles and their decays in the presence of R-parity-violating couplings is discussed together with a survey of existing constraints from collider experiments.

MODELS OF PARTICLE PHYSICS FROM TYPE IIB STRING THEORY AND F-THEORY: A REVIEW (2012, background): “straints on the higher dimension operator vary according to which generations are involved in the operator, with the strongest constraint in the case with the largest number of light generations (see [295] for a review of the constraints). Therefore a full understanding of the constraints on such op”
Searching for long-lived particles beyond the Standard Model at the Large Hadron Collider (2019, background): “The SUSY model mandates a near-massless invisible particle, while other models (such as DM theories [127, 149]) allow for a heavy invisible particle.”
The State of Supersymmetry after Run I of the LHC (2013, background): “Thus the total parameter counting involves 3 dimensionful parameters μi, 9 λ, 27 λ ′, 9 λ′′, giving us 48 new (possibly complex) parameters in total [58].”

Colored resonant signals at the LHC: largest rate and simplest topology (2010, background): “We note that the color-triplet scalars (U3, D3) resemble scalar quarks (ũ, d̃) in SUSY and the interactions (with the chirality τ = L) are directly analogous to R-parity violating operators of the λ terms [1], or the “diquarks” [2].”
Model-independent constraints on new physics in b → s transitions (2011, methodology): “For example, in the MSSM with MFV and flavour blind phases [81], in effective SUSY with flavour blind phases [82] and in effective SUSY with a U(2)3 symmetry [83, 84], NP effects in ∆B = ∆S = 1 processes arise almost exclusively through complex contributions to C7 (and C8).”
Proton stability in grand unified theories, in strings and in branes (2006, methodology): “However, only recently the bounds coming from proton decay have been achieved taking into account flavor mixing and using the chiral lagrangian techniques [63] (For several phenomenological aspects of R parity violating interactions see references [64, 65, 66]).”
Naturalness and the Status of Supersymmetry (2013, background): “In fact, there are stringent bounds on individual RPV couplings, and even more stringent bounds on products of pairs of couplings [164, 165]; in particular, if any lepton number-violating coupling and any baryon number-violating coupling are both non-zero, proton decay sets extremely stringent const”
Search for massive, long-lived particles using multitrack displaced vertices or displaced lepton pairs in pp collisions at $\sqrt{s}$ = 8 TeV with the ATLAS detector (2015, background): “Decays of the neutralino into a neutrino and light leptons, which may be e þ e − , μ þ μ − , or e (cid:2) μ ∓ , take place due to the nonzero values of the RPV couplings λ 121 and λ 122 [2].”
Probing the Standard Model with Higgs signal rates from the Tevatron, the LHC and a future ILC (2014, background): “Other examples can be found in theories beyond the SM, like for instance, decays to supersymmetric particles that further decay via SUSY cascades or via R-parity violating interactions [97, 98], which also potentially leading to detached vertices.”
Physics of leptoquarks in precision experiments and at particle colliders (2016, background): “We do not, however, intend to cover physics of R-parity violation and instead point the reader to extensive reviews and studies on the subject [44, 45, 46, 47, 48, 42, 49, 50].”
Heterotic line bundle standard models (2012, background): “Dimension four proton decay operators are tightly constrained by experiments to have coefficients less that 10−6 for any combination of generation indices [54].”
Natural SUSY endures (2011, background): “On the other hand, if the LHC experiments fail to discover supersymmetry in the natural parameter space then, as the fine-tuning is increased, exotic manifestations of supersymmetry that are less constrained, such as hadronic R-parity violation [159] or stealth SUSY [143], will become increasingly m”
From the Trees to the Forest: A Review of Radiative Neutrino Mass Models (2017, background): “The non-observation of processes violating these symmetries impose strong constraints on these parameters, which are required to be rather small [646].”
Higgs Physics at the HL-LHC and HE-LHC (2019, background): “The presence of long-lived particles (LLP) can be a striking feature of many new physics models [802, 803, 804, 805, 806, 807, 808, 809, 810, 811, 812, 813].”
