Editing Hierarchy problem (section)

==== UV/IR mixing ====
In 2019, a pair of researchers proposed that [[IR/UV mixing]] resulting in the breakdown of the [[effective field theory|effective]] [[quantum field theory]] could resolve the hierarchy problem.<ref>{{cite journal|title=IR dynamics from UV divergences: UV/IR mixing, NCFT, and the hierarchy problem|first1=Nathaniel|last1=Craig|first2=Seth|last2=Koren|journal=Journal of High Energy Physics|doi=10.1007/JHEP03(2020)037|date=6 March 2020|volume=2020|issue=37|page=37|arxiv=1909.01365|bibcode=2020JHEP...03..037C|s2cid=202540077}}</ref> In 2021, another group of researchers showed that UV/IR mixing could resolve the hierarchy problem in string theory.<ref>{{cite journal|title=Calculating the Higgs mass in string theory|first1=Steven|last1=Abel|first2=Keith R.|last2=Dienes|journal=Physical Review D|volume=104|issue=12|date=29 December 2021|page=126032|doi=10.1103/PhysRevD.104.126032|arxiv=2106.04622|bibcode=2021PhRvD.104l6032A|s2cid=235377340}}</ref>
