We examine a possibility that pseudo Nambu-Goldstone bosons account for both hot and cold dark matter components. We show that the QCD axions can do the job for the axion decay constant f_a < O(10^10) GeV, if they are produced by the saxion decay and the domain wall annihilation. We also investigate the cases of thermal QCD axions, pseudo Nambu-Goldstone bosons coupled to the standard model sector through the Higgs portal, and axions produced by modulus decay. 000154830 536__ $$0G:(DE-HGF)POF2-514$$a514 - Theoretical Particle Physics (POF2-514)$$cPOF2-514$$fPOF II$$x0 000154830 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000154830 7001_ $$0P:(DE-HGF)0$$aKawasaki, Masahiro$$b1 000154830 7001_ $$0P:(DE-HGF)0$$aTakahashi, Fuminobu$$b2 000154830 8564_ $$uhttps://arxiv.org/abs/1310.1774 000154830 8564_ $$uhttps://bib-pubdb1.desy.de/record/154830/files/DESY-2013-01123.pdf$$yRestricted 000154830 8564_ $$uhttps://bib-pubdb1.desy.de/record/154830/files/DESY-2013-01123.jpg?subformat=icon-1440$$xicon-1440$$yRestricted 000154830 8564_ $$uhttps://bib-pubdb1.desy.de/record/154830/files/DESY-2013-01123.jpg?subformat=icon-180$$xicon-180$$yRestricted 000154830 8564_ $$uhttps://bib-pubdb1.desy.de/record/154830/files/DESY-2013-01123.jpg?subformat=icon-640$$xicon-640$$yRestricted 000154830 909CO $$ooai:bib-pubdb1.desy.de:154830$$pVDB 000154830 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-HGF)0$$aDeutsches Elektronen-Synchrotron$$b0$$kDESY 000154830 9131_ $$0G:(DE-HGF)POF2-514$$1G:(DE-HGF)POF2-510$$2G:(DE-HGF)POF2-500$$3G:(DE-HGF)POF2$$4G:(DE-HGF)POF$$aDE-HGF$$bStruktur der Materie$$lElementarteilchenphysik$$vTheoretical Particle Physics$$x0 000154830 9141_ $$y2013 000154830 915__ $$0StatID:(DE-HGF)0580$$2StatID$$aPublished 000154830 9201_ $$0I:(DE-H253)T-20120731$$kT$$lTheorie-Gruppe$$x0 000154830 980__ $$apreprint 000154830 980__ $$aVDB 000154830 980__ $$aUNRESTRICTED 000154830 980__ $$aintrep 000154830 980__ $$aI:(DE-H253)T-20120731
