The LHCb collaboration has reported an intriguing new result in its quest to test a key principle of the Standard Model called lepton universality. Although not statistically significant, the finding ...
This is the fourteenth workshop of this series devoted to physics of the τ lepton and its associated neutrino. The goal of the workshop is to get theorists and experimentalists together to discuss rec...
Quark and lepton masses and mixing in the landscape
Lepton yukawa coupling matrix element
2014/12/20
Even if quark and lepton masses are not uniquely predicted by the fundamental theory, as may be the case in the string theory landscape, nevertheless their pattern may reveal features of the underlyin...
Studies of Vertex Tracking with SOI Pixel Sensors for Future Lepton Colliders
Monolithic pixel sensor SOI technology Vertex reconstruction High Energy Physics - Experiment
2012/4/24
This paper presents a study of vertex tracking with a beam hodoscope consisting of three layers of monolithic pixel sensors in SOI technology on high-resistivity substrate. We study the track extrapol...
Hidden SUSY at the LHC: the light higgsino-world scenario and the role of a lepton collider
Supersymmetry Phenomenology Supersymmetric Standard Model Large Hadron Collider
2011/10/14
While the SUSY flavor, CP and gravitino problems seem to favor a very heavy spectrum of matter scalars, fine-tuning in the electroweak sector prefers low values of superpotential mass \mu. In the limi...

Top-quark pair cross-section measurement lepton+jets channel
2011/9/14
ps =7 TeV is presented using data recorded with the ATLAS detector at the Large Hadron Collider (LHC). Events are selected in the lepton+jets topology by requiring a single lepton (electron or muon), ...

Search for supersymmetry using final states with one lepton, jets, and missing transverse momentum with the ATLAS detector in sqrt{s} = 7 TeV pp 。
The observation of astrophysical neutrinos requires a detailed understanding of the atmospheric neutrino background. Since neutrinos are produced in meson decays together with a charged lepton, import...
Lepton flavor violating New Physics and supernova explosion
Lepton flavor violating New Physics supernova explosion
2011/1/13
Electrons and electron neutrinos in the inner core of the core-collapse supernova are highly degenerate and therefore numerous during a few seconds of explosion. In contrast, leptons of other flavors ...
Lepton number violation in theories with a large number of Standard Model copies
Lepton number violation Standard Model copies
2010/12/27
We examine lepton number violation (LNV) in theories with a saturated black hole bound on a large number of species. Such theories have been advocated recently as a possible solution to the hierarchy ...
Phenomenological constraints on minimally coupled exotic lepton triplets
Phenomenological constraints minimally coupled exotic lepton triplets
2011/1/5
By introducing a set of new triplet leptons (with nonzero hypercharge) that can Yukawa couple
to their Standard Model counterparts, new sources of tree-level flavor changing currents are induced via ...

The nucleon's transversity the photon's distribution amplitude probed lepton pair photoproduction
2010/12/29
We describe a new way to access the chiral odd transversity parton distribution in the proton through the photoproduction of lepton pairs on transversely polarized target. The basic ingredient is the ...

Neutrinos physics of the early universe primordial asymmetries
2010/11/10
We study the evolution of primordial neutrino{antineutrino asymmetries in the early universe, before and during Big Bang Nucleosynthesis (BBN). We consider quite a wide range for the total lepton numb...
