Flavor-singlet hybrid baryons may already have been discovered
- Physics
- 2005
The splittings between the spin 1/2 and spin 3/2 iso-singlet baryons Lambda_s(1405) and Lambda_s(1520), and their charmed counterparts Lambda_c(2593) and Lambda_c(2625), have been a theoretical…
Dibaryons cannot be the dark matter
- PhysicsPhysical Review D
- 2019
The hypothetical $SU(3)$ flavor-singlet dibaryon state $S$ with strangeness $-2$ has been discussed as a dark-matter candidate capable of explaining the curious 5-to-1 ratio of the mass density of…
6-quark Dark Matter
- Physics
- 2017
It has recently been proposed that the relatively inert, highly symmetric, neutral flavor singlet scalar hadron made of uuddss quarks may have a mass < 2 (m_p + m_e). This is consistent with QCD…
Alternative Approaches to Dark Matter Puzzle
- Physics
- 2005
We study the dark matter problem with particular reference to a candidate particle within the Standard Model: the $H$ dibaryon. We consider as well a scenario which aims to connect the dark matter…
Resonant Scattering between Dark Matter and Baryons: Revised Direct Detection and CMB Limits
- Physics
- 2021
Traditional dark matter (DM) models, eg. WIMPs, assume dark matter is weakly coupled to the standard model so that elastic scattering between DM and baryons can be described perturbatively by Born…
Quark deconfinement in compact stars through sexaquark condensation
- Physics
- 2022
In this contribution, we present for the first time a scenario according to which early quark deconfinement in compact stars is triggered by the Bose-Einstein condensation (BEC) of a light sexaquark…
The scalar hexaquark uuddss: a candidate to dark matter?
- Physics
- 2019
It is conventionally argued that Dark Matter (DM) has a non-baryonic nature, but if we assume that DM was frozen out before primordial nucleosynthesis and could not significantly impact primordial…
Transitions of two baryons to the H dibaryon in nuclei
- Physics
- 2003
We calculate the suppression in the rate at which two baryons in a nucleus (viz., nucleons or $\Lambda$'s) convert to an H dibaryon, using an Isgur-Karl wavefunction for quarks in the baryons and H,…
Floating Dark Matter in Celestial Bodies
- Physics, Geology
- 2022
Dark matter (DM) can be captured in celestial bodies after scattering and losing sufficient energy to become gravitationally bound. We derive a general framework that describes the current DM…
Colored dark matter
- PhysicsPhysical Review D
- 2018
We explore the possibility that Dark Matter is the lightest hadron made of two stable color octet Dirac fermions ${\cal Q}$. The cosmological DM abundance is reproduced for $M_{\cal Q}\approx 9.5$…

Ultrahigh-energy cosmic rays and stable H dibaryon
- Physics
- 1999
It is shown that an instanton-induced interaction between quarks produces a very deeply bound H dibaryon with mass below 2MN, viz., MH=1718 MeV. Therefore the H dibaryon is predicted to be a stable…
Light Gluinos
- Physics
- 1994
: Gluino and lightest neutralino masses are naturally less than a few GeV if dimension-3 susy-breaking operators are absent from the low energy theory. In this case gaugino masses come from loops and…
An accurate nucleon-nucleon potential with charge-independence breaking
- Physics
- 1994
We present a new high-quality nucleon-nucleon potential with explicit charge dependence and charge asymmetry, which we designate Argonne v18. The model has a charge-independent part with fourteen…
Comments on glueballinos (R0 particles) and R0 searches
- Physics
- 1996
We propose a search strategy for the light R0 (glueballino) particle suggested by G.Farrar in connection with the light gluino scenario. The basic idea is to moderate and stop the R0 particles and…
The Non-Local Nature of the Nuclear Force and its Impact on Nuclear Structure
- Physics

We calculate the triton binding energy with a non-local NN potential that fits the world NN data below 350 MeV with the almost perfect χ 2 /datum of 1.03. The non-locality is derived from relativistic…

Search for low-Z nuclei containing massive stable particles.
- PhysicsPhysical review. D, Particles and fields
- 1990
A search for massive isotopes of hydrogen, lithium, beryllium, boron, carbon, oxygen, and fluorine was performed using an electrostatic charged-particle spectrometer in conjunction with a tandem accelerator, finding no evidence for stable isotopes with masses between 100 and 10 000 amu.
How to search for primordial light gluinos.
- PhysicsPhysical review. D, Particles and fields
- 1995
The phenomenology of light primordial gluinos is studied in order to set limits on their abundance and to suggest new search strategies for hadronic gluino states.
