abstract
The recent observation of $^4$He implies that our universe has a large lepton asymmetry. We consider the Affleck-Dine (AD) mechanism for lepton number generation. In the AD mechanism, non-topological solitons called L-balls are produced, and the generated lepton number is confined in them. The L-balls protect the generated lepton number from being converted to baryon number through the sphaleron processes. We study the formation and evolution of the L-balls and find that the universe with large lepton asymmetry suggested by the recent $^4$He measurement can be realized.

Heavy neutral leptons beyond the BBN bound: probing the lepton asymmetry of the Universe
A Dirac heavy neutral lepton with a particle-antiparticle asymmetry can evade the hadronic BBN bound by injecting charged pions that restore the standard neutron abundance, opening sub-GeV parameter space accessible to SHiP.

Cogenesis of baryon and lepton number asymmetries matching the EMPRESS Data
A U(1)_{B-L} flaton decay chain can produce both a large positive electron-neutrino asymmetry and the observed baryon asymmetry, with values matching EMPRESS and BBN for a symmetry-breaking scale around 10^10 GeV.

Neutrinophilic $\mathbf{\Lambda}$CDM Extension for EMPRESS, DESI and Hubble Tension
A combined fit of EMPRESS, DESI BAO, and CMB data prefers a neutrino asymmetry xi_nu = 0.056 +/- 0.017 and extra radiation delta_Neff = 0.41 +/- 0.16 in a neutrinophilic LambdaCDM model.
