Lepton asymmetric universe

Journal of Cosmology and Astroparticle Physics, 2022
AbstractThe recent observation of4He 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.

Jet shape and redistribution of the lost energy from jets in Pb + Pb collisions at the LHC in a multiphase transport model

European Physical Journal C: Particles and Fields, 2022
Jet-medium interaction involves two important effects: jet energy loss and medium response. The search for jet-induced medium excitations is one of the hot topics in jet quenching study in relativistic nuclear collisions.

Leptonic unitarity triangles [PDF]

Physical Review D, 2020
We present a comprehensive analysis of leptonic unitarity triangles, using both current neutrino oscillation data and projections of next-generation oscillation measurements. Future experiments, sensitive to the degree of CP violation in the lepton sector, will enable the construction of precise triangles. We show how unitarity violation could manifest

Large lepton asymmetry from Q-balls [PDF]

, 2002
We propose a scenario which can explain large lepton asymmetry and small baryon asymmetry simultaneously. Large lepton asymmetry is generated through Affleck-Dine (AD) mechanism and almost all the produced lepton numbers are absorbed into Q-balls (L ...

Leptonic and semi-leptonic B decays [PDF]

Nuclear Physics B - Proceedings Supplements, 2001
We present results for the semi-leptonic and leptonic decays of B mesons. These non-perturbative matrix elements are important for constraining the CKM matrix. Results are presented for the pseudoscalar and vector decay constants, as well as flavour breaking ratios and heavy quark symmetry relations.

Combined explanations of B-physics anomalies, $$(g-2)_{e, \mu }$$ ( g - 2 ) e , μ and neutrino masses by scalar leptoquarks

European Physical Journal C: Particles and Fields, 2022
We extend the contents of the standard model (SM) by introducing TeV-scale scalar leptoquarks to generate neutrino masses and explain some current observed deviations from the SM predictions, including the anomalous magnetic moments of charged leptons ...

Softly broken lepton numbers and maximal neutrino mixing [PDF]

, 2001
We consider lepton mixing in an extension of the Standard Model with three right-handed neutrino singlets. We require that the three lepton numbers L_e, L_\mu, and L_\tau be separately conserved in the Yukawa couplings, and we assume that they are softly

Search for medium response to jet quenching via hadron chemistry around the quenched jets [PDF]

EPJ Web of Conferences
We present a unique signal of medium response to jet quenching: the enhancement of baryon-to-meson ratios for associated particles at intermediate transverse momentum around the triggered quenched jets.

Lepton Flavor Violation in Supersymmetric SO(10) Grand Unified Models [PDF]

, 2000
The study for lepton flavor violation combined with the neutrino oscillation may provide more information about the lepton flavor structure of the grand unified theory.

Probing QCD critical fluctuations from intermittency analysis in relativistic heavy-ion collisions

Physics Letters B, 2020
It is shown that intermittency, a self-similar correlation with respect to the size of the phase space volume, is sensitive to critical density fluctuations of baryon numbers in a system belonging to the three-dimensional (3D) Ising universality class ...
