Abstract

The rate for proton decay to the e⁺γ mode is calculated. Although its branching ratio is of order α, its ratio to observable e⁺π⁰ correlated decays is $18 to 140$ . Observable numbers of p → e⁺ + γ decays can occur and would provide constraints on the proton wave function at the origin and grand unified parameters independent of hadron final state uncertainties.

Proton stability in grand unified theories, in strings and in branes
2007, Physics Reports
A broad overview of the current status of proton stability in unified models of particle interactions is given which includes non-supersymmetric unification, SUSY and SUGRA unified models, unification based on extra dimensions, and string-M-theory models. The extra dimensional unification includes 5D and 6D and universal extra dimensional (UED) models, and models based on warped geometry. Proton stability in a wide array of string theory and M theory models is reviewed. These include Calabi–Yau models, grand unified models with Kac–Moody levels $k > 1$ , a new class of heterotic string models, models based on intersecting D branes, and string landscape models. The destabilizing effect of quantum gravity on the proton is discussed. The possibility of testing grand unified models, models based on extra dimensions and string-M-theory models via their distinctive modes is investigated. The proposed next generation proton decay experiments, HyperK, UNO, MEMPHYS, ICARUS, LANNDD (DUSEL), and LENA would shed significant light on the nature of unification complementary to the physics at the LHC. Mathematical tools for the computation of proton lifetime are given in the appendices. Prospects for the future are discussed.
Fermion mixings vs d = 6 proton decay
2004, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
It is well known, although sometimes ignored, that not only the d=5 but also d=6 proton decay depends on fermion mixings. In general we study carefully the dependence of d=6 decay on fermion mixings using the effective operator approach. We find that without specifying a theory it is impossible to make clear predictions. Even in a given model, it is often not possible to determine all the physical parameters. We point out that it is possible to make a clear test of any grand unified theory with symmetric Yukawa couplings. We discuss in some detail realistic theories based on SU(5) and SO(10) gauge symmetry.
The properties of charmed baryon (Λ<inf>c</inf><sup>+</sup>) and the proton revisited
1983, Annals of Physics
A statistical model for baryons was suggested leading to an analytical expression for the square modulus ∥ψ(r)∥² of baryon wavefunctions, which is not only free of constituent quark masses but also devoid of the interaction parameters of the effective linear potential in which a quark moves. Using ∥ψ(r)∥² as an input the lifetimes of the newly established charmed baryon ( $Λ_{c}^{+}$ ) and the proton were studied and compared with other existing theoretical estimates.
Relevance of the 3<inf>q</inf>-annihilation and the radiative proton decay
1982, Physics Letters B
Study of some nuclear contributions to the lifetime of the proton
1982, Physics Letters B
Using a Fermi gas model for the nuclear motion, we compute the decay rate of a nucleus, due to the mechanism of one-pion exchange between nucleons. In one of the modes, this contribution to the total lifetime of the proton is up to 40 percent of what gets in the disintegration of isolated nucleons. The experimental signature of these nuclear events is different. Recoiling against a lepton-pion pair a nucleon should appear.
