Stochastic Selection of Cosmological Constant in Chaotic Inflation: A String Theory Landscape Approach

a. Telescope: Simons Observatory, CMB-S4.

b. Target:

B-mode detection with sensitivity (r)<0.001   p(r)<0.001.

Search for statistical anomalies in galaxy distributions (LSST, Euclid).

5. Discussion & Conclusion

a. with Data: Prediction model r0.003  r0.003, consistent with Planck 2018.

b. Criticism:

The size problem in the multiverse.

Reliance on unconfirmed string theory parameters.

c. The next step:

Full-string theory simulations on supercomputers.
