Particle physics theoretical and experimental studies

The mission of the European Space Agency will deliver weak gravitational lensing and galaxy clustering surveys that can be used to constrain the standard cosmological model and extensions thereof. We present forecasts from the combination of the photometric galaxy surveys (weak lensing, galaxy clustering, and their cross-correlations) and its spectroscopic redshift survey with respect to their sensitivity to cosmological parameters. We include the summed neutrino mass, smnu , and the effective number of relativistic species, neff , in the standard Lambda CDM scenario and in the dynamical dark energy ($w_0 w_a$CDM) scenario. We compared the accuracy of different algorithms predicting the non-linear matter power spectrum for such models. We then validated several pipelines for Fisher matrix and Markov chain Monte Carlo (MCMC) forecasts, using different theory codes, algorithms for numerical derivatives, and assumptions on the non-linear cut-off scale. The primary probes alone will reach a sensitivity of $ meV meV $ in the Lambda CDM+smnu model, whereas the combination with cosmic microwave background (CMB) data from is expected to achieve $ meV $, offering evidence of a non-zero neutrino mass to at least the $2.6\ level. This could be pushed to a $4\ detection if future CMB data from LiteBIRD and CMB Stage-IV were included. In combination with will also deliver tight constraints on $ 0.144$ (95<!PCT!>CL) in the Lambda CDM+smnu +neff model or even $ 0.063$ when future CMB data are included. When floating the dark energy parameters, we find that the sensitivity to neff remains stable, but for smnu , it gets degraded by up to a factor of 2, at most. This work illustrates the complementarity among the spectroscopic and photometric surveys and among and CMB constraints. will offer great potential in measuring the neutrino mass and excluding well-motivated scenarios with additional relativistic particles.
