Darkon is a hypothetical scalar unparticle to introduce to the Minimal Supersymmetric Standard Model, a dark matter candidate.{{cite journal |last1=Jia |first1=Lian-Bao |last2=Li |first2=Xue-Qian |title=Study of a WIMP dark matter model with the updated results of CDMS II |journal=Physical Review D |date=13 February 2014 |volume=89 |issue=3 |pages=035006 |doi=10.1103/PhysRevD.89.035006 |arxiv=1309.6029 |bibcode=2014PhRvD..89c5006J |s2cid=118570160 |issn=1550-7998}}{{cite journal |last1=Xiao-Gang |first1=He |title=Darkon dark matter, unparticle effects and collider physics |journal=Chinese Physics C |date=June 2009 |volume=33 |issue=6 |pages=451–455 |doi=10.1088/1674-1137/33/6/010 |s2cid=250794700 |url=https://iopscience.iop.org/article/10.1088/1674-1137/33/6/010 |access-date=7 January 2023 |issn=1674-1137|url-access=subscription }}{{cite journal |last1=Cai |first1=Yi |last2=He |first2=Xiao-Gang |last3=Ren |first3=Bo |title=Low Mass Dark Matter and Invisible Higgs Width In Darkon Models |journal=Physical Review D |pages=083524 |doi=10.1103/PhysRevD.83.083524 |date=28 April 2011|volume=83 |issue=8 |arxiv=1102.1522 |bibcode=2011PhRvD..83h3524C |s2cid=119204162 }}{{cite journal |last1=Stichel |first1=P.

History
A. Zee and V. Silveira were the first to consider the darkon field as dark matter in 1985. This approach was then used by several others groups of physicists.{{cite journal |last1=He |first1=Xiao-Gang |last2=Li |first2=Tong |last3=Li |first3=Xue-Qian |last4=Tandean |first4=Jusak |last5=Tsai |first5=Ho-Chin |title=Constraints on Scalar Dark Matter from Direct Experimental Searches |journal=International Journal of Modern Physics: Conference Series |date=January 2011 |volume=01 |pages=257–265 |doi=10.1142/S2010194511000377 |bibcode=2011IJMPS...1..257H |url=https://www.worldscientific.com/doi/abs/10.1142/S2010194511000377 |access-date=7 January 2023|arxiv=0811.0658 }}{{cite journal |last1=Cheung |first1=Kingman |last2=Tsai |first2=Yue-Lin S. |last3=Tseng |first3=Po-Yan |last4=Yuan |first4=Tzu-Chiang |last5=Zee |first5=A. |title=Global Constraints of the Simplest Darkon Model |journal=Nuclear Physics B - Proceedings Supplements |date=1 January 2014 |volume=246-247 |pages=116–126 |doi=10.1016/j.nuclphysbps.2013.10.074 |bibcode=2014NuPhS.246..116C |url=https://www.sciencedirect.com/science/article/abs/pii/S0920563213006634 |access-date=7 January 2023 |language=en |issn=0920-5632|url-access=subscription }}
Concept
In addition to the Standard Model particles, It contains the darkon, a real singlet field. To play the role of dark matter, the darkon field must interact weakly with the standard matter field sector and should not rapidly decay into particles. The simplest way of introducing the darkon is to demand that they can only be annihilated or created in pairs and to make it stable against decay.
