As a first step, we recalculate alpha-alpha scattering in our Universe utilizing various improvements in the adiabatic projection method, which leads to an improved, parameter-free prediction of the S- and D-wave phase shifts for laboratory energies below 10 MeV. We find that positive shifts in the pion mass have a small effect on the S-wave phase shift, whereas lowering the pion mass adds some repulsion in the two-alpha system. The effect on the D-wave phase shift turns out to be more pronounced as signaled by the D-wave resonance parameters. Variations of the fine-structure constant have almost no effect on the low-energy alpha-alpha phase shifts. We further show that up-to-and-including next-to-leading order in the chiral expansion, variations of these phase shifts with respect to the QCD theta-angle can be expressed in terms of the theta-dependent pion mass. 000910663 536__ $$0G:(DE-HGF)POF4-5111$$a5111 - Domain-Specific Simulation Data Life Cycle Labs (SDLs) and Research Groups (POF4-511)$$cPOF4-511$$fPOF IV$$x0 000910663 536__ $$0G:(GEPRIS)196253076$$aDFG project 196253076 - TRR 110: Symmetrien und Strukturbildung in der Quantenchromodynamik (196253076)$$c196253076$$x1 000910663 536__ $$0G:(DE-Juel1)jara0015_20200501$$aNuclear Lattice Simulations (jara0015_20200501)$$cjara0015_20200501$$fNuclear Lattice Simulations$$x2 000910663 588__ $$aDataset connected to CrossRef, Journals: juser.fz-juelich.de 000910663 7001_ $$0P:(DE-Juel1)145995$$aLähde, Timo A.$$b1$$ufzj 000910663 7001_ $$0P:(DE-HGF)0$$aLee, Dean$$b2 000910663 7001_ $$0P:(DE-Juel1)131252$$aMeißner, Ulf-G.$$b3 000910663 7001_ $$0P:(DE-HGF)0$$aVonk, Thomas$$b4 000910663 773__ $$0PERI:(DE-600)2027350-2$$a10.1007/JHEP02(2022)001$$gVol. 2022, no. 2, p. 1$$n2$$p1$$tJournal of high energy physics$$v2022$$x1029-8479$$y2022 000910663 8564_ $$uhttps://juser.fz-juelich.de/record/910663/files/JHEP02%282022%29001.pdf$$yOpenAccess 000910663 909CO $$ooai:juser.fz-juelich.de:910663$$pdnbdelivery$$pdriver$$pVDB$$popen_access$$popenaire 000910663 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)145995$$aForschungszentrum Jülich$$b1$$kFZJ 000910663 9101_ $$0I:(DE-HGF)0$$6P:(DE-HGF)0$$aExternal Institute$$b2$$kExtern 000910663 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)131252$$aForschungszentrum Jülich$$b3$$kFZJ 000910663 9101_ $$0I:(DE-HGF)0$$6P:(DE-HGF)0$$aExternal Institute$$b4$$kExtern 000910663 9131_ $$0G:(DE-HGF)POF4-511$$1G:(DE-HGF)POF4-510$$2G:(DE-HGF)POF4-500$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF4-5111$$aDE-HGF$$bKey Technologies$$lEngineering Digital Futures – Supercomputing, Data Management and Information Security for Knowledge and Action$$vEnabling Computational- & Data-Intensive Science and Engineering$$x0 000910663 9141_ $$y2022 000910663 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2021-01-30 000910663 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000910663 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000910663 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2021-01-30 000910663 915__ $$0StatID:(DE-HGF)0570$$2StatID$$aSCOAP3 000910663 915__ $$0StatID:(DE-HGF)0571$$2StatID$$aDBCoverage$$bSCOAP3 sponsored Journal$$d2021-01-30 000910663 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz$$d2022-11-12$$wger 000910663 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2022-11-12 000910663 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline$$d2022-11-12 000910663 915__ $$0StatID:(DE-HGF)0600$$2StatID$$aDBCoverage$$bEbsco Academic Search$$d2022-11-12 000910663 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bASC$$d2022-11-12 000910663 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bJ HIGH ENERGY PHYS : 2021$$d2022-11-12 000910663 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal$$d2022-09-27T19:53:18Z 000910663 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ$$d2022-09-27T19:53:18Z 000910663 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Blind peer review$$d2022-09-27T19:53:18Z 000910663 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2022-11-12 000910663 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2022-11-12 000910663 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences$$d2022-11-12 000910663 915__ $$0StatID:(DE-HGF)9905$$2StatID$$aIF >= 5$$bJ HIGH ENERGY PHYS : 2021$$d2022-11-12 000910663 920__ $$lyes 000910663 9201_ $$0I:(DE-Juel1)IAS-4-20090406$$kIAS-4$$lTheorie der Starken Wechselwirkung$$x0 000910663 980__ $$ajournal 000910663 980__ $$aVDB 000910663 980__ $$aUNRESTRICTED 000910663 980__ $$aI:(DE-Juel1)IAS-4-20090406 000910663 9801_ $$aFullTexts
