Lepton flavor violation in the supersymmetric standard model with vectorlike leptons [PDF]
Phys.Rev. D62 (2000) 073007, 2000 Lepton flavor violating processes are obtained from the mixing between ordinary leptons and vectorlike SU(2)_L doublet leptons which may originate in E_6. The effects of this lepton mixing are, however, suppressed naturally by the hierarchy of the charged lepton masses.

The leptonic future of the Higgs [PDF]
Journal of High Energy Physics, 2017 Precision study of electroweak symmetry breaking strongly motivates the construction of a lepton collider with center-of-mass energy of at least 240 GeV. Besides Higgsstrahlung ($e^+e^- \to hZ$), such a collider would measure weak boson pair production ($e^+e^- \to WW$) with an astonishing precision.

Lepton PDFs and multipurpose single-lepton searches at the LHC
Physical Review D, 2023 A final state consisting of one charged lepton, at least one jet, and little missing transverse energy can be a very promising signature of new physics at the LHC across a wide range of models. However, it has received only limited attention so far. In this work we discuss the potential sensitivity of this channel to various new physics scenarios.

The decomposition of neutron-antineutron oscillation operators
Journal of High Energy Physics, 2023 We study the systematic decomposition of the dimension nine neutron-antineutron oscillation operators at tree and one-loop levels. We discuss the topologies’ generation and the assignment of the chiral quarks.

Sensitivity of future lepton colliders and low-energy experiments to charged lepton flavor violation from bileptons [PDF]
Phys. Rev. D 100, 115007 (2019), 2019 The observation of charged lepton flavor violation is a clear sign of physics beyond the Standard Model (SM). In this work, we investigate the sensitivity of future lepton colliders to charged lepton flavor violation via on-shell production of bileptons, and compare their sensitivity with current constraints and future sensitivities of low-energy ...

The global geometrical property of jet events in high-energy nuclear collisions
European Physical Journal C: Particles and Fields, 2020 We present the first theoretical study of medium modifications of the global geometrical pattern, i.e., transverse sphericity ( $$S_{\perp }$$ S ⊥ ) distribution of jet events with parton energy loss in relativistic heavy-ion collisions.

Machine learning of pair-contact process with diffusion
Scientific Reports, 2022 The pair-contact process with diffusion (PCPD), a generalized model of the ordinary pair-contact process (PCP) without diffusion, exhibits a continuous absorbing phase transition.

Il Nuovo Cimento, 1962 If the electron and its associated neutrino v and the muon and its associated neutrino u are put into two isodoublets, then a strangeness-conserving isovector weak 4-currentJλ can be defined such that weak interaction ∞Jλ·Jλ conserves isospin. The « neutral currents » so introduced do not affect the rates of Β-decay, Μ-capture, etc., predict no ...
