In these models the potential energy has a monomial form over a super-Planckian field range, with superimposed modulations whose size is model-dependent. The amplitude and frequency of the modulations are set by the expectation values of moduli fields. We show that during the course of inflation, the diminishing energy density can induce slow adjustments of the moduli, changing the modulations. We provide templates capturing the effects of drifting moduli, as well as drifts arising in effective field theory models based on softly broken discrete shift symmetries, and we estimate the precision required to detect a drifting period. A non-drifting template suffices over a wide range of parameters, but for the highest frequencies of interest, or for sufficiently strong drift, it is necessary to include parameters characterizing the change in frequency over the e-folds visible in the CMB. We use these templates to perform a preliminary search for drifting oscillations in a part of the parameter space in the Planck nominal mission data. 000193123 536__ $$0G:(DE-HGF)POF2-514$$a514 - Theoretical Particle Physics (POF2-514)$$cPOF2-514$$fPOF II$$x0 000193123 588__ $$aDataset connected to arXivarXiv 000193123 650_7 $$2INSPIRE$$amodulation: frequency 000193123 650_7 $$2INSPIRE$$apower spectrum: primordial 000193123 650_7 $$2INSPIRE$$apotential: energy 000193123 650_7 $$2INSPIRE$$aoscillation 000193123 650_7 $$2INSPIRE$$amoduli 000193123 650_7 $$2INSPIRE$$ainflation 000193123 650_7 $$2INSPIRE$$amonodromy 000193123 650_7 $$2INSPIRE$$aaxion 000193123 650_7 $$2INSPIRE$$acosmic background radiation 000193123 650_7 $$2INSPIRE$$aeffective field theory 000193123 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000193123 7001_ $$0P:(DE-HGF)0$$aMcAllister, Liam$$b1 000193123 7001_ $$0P:(DE-HGF)0$$aSilverstein, Eva$$b2 000193123 7001_ $$0P:(DE-H253)PIP1013212$$aWestphal, Alexander$$b3$$udesy 000193123 773__ $$y2014 000193123 8564_ $$uhttp://arxiv.org/abs/arXiv:1412.1814 000193123 8564_ $$uhttps://bib-pubdb1.desy.de/record/193123/files/PUBDB-2014-04552.pdf$$yOpenAccess 000193123 8564_ $$uhttps://bib-pubdb1.desy.de/record/193123/files/PUBDB-2014-04552.gif?subformat=icon$$xicon$$yOpenAccess 000193123 8564_ $$uhttps://bib-pubdb1.desy.de/record/193123/files/PUBDB-2014-04552.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000193123 8564_ $$uhttps://bib-pubdb1.desy.de/record/193123/files/PUBDB-2014-04552.jpg?subformat=icon-700$$xicon-700$$yOpenAccess 000193123 8564_ $$uhttps://bib-pubdb1.desy.de/record/193123/files/PUBDB-2014-04552.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000193123 8564_ $$uhttps://bib-pubdb1.desy.de/record/193123/files/PUBDB-2014-04552.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000193123 909CO $$ooai:bib-pubdb1.desy.de:193123$$pdriver$$pVDB$$popen_access$$popenaire 000193123 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1013212$$aDeutsches Elektronen-Synchrotron$$b3$$kDESY 000193123 9132_ $$0G:(DE-HGF)POF3-611$$1G:(DE-HGF)POF3-610$$2G:(DE-HGF)POF3-600$$aDE-HGF$$bForschungsbereich Materie$$lMaterie und Universum$$vFundamental Particles and Forces $$x0 000193123 9131_ $$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$$x0 000193123 9141_ $$y2014 000193123 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000193123 9201_ $$0I:(DE-H253)T-20120731$$kT$$lTheorie-Gruppe$$x0 000193123 980__ $$aintrep 000193123 980__ $$aVDB 000193123 980__ $$aUNRESTRICTED 000193123 980__ $$aFullTexts 000193123 980__ $$aI:(DE-H253)T-20120731 000193123 9801_ $$aFullTexts
