Constraints on neutrino oscillation parameters from the measurement of day-night solar neutrino fluxes at Super-Kamiokande

Posted by klaurent Tokyo

Kavli Affiliate: Kunio Inoue | Summary:A search for day-night variations in the solar neutrino flux resulting from neutrino oscillations has been carried out using the 504 day sample of solar neutrino data obtained at Super-Kamiokande. The absence of a significant day-night variation has set an absolute flux independent exclusion region in the two neutrino oscillation […]

Imaging Electron Wave Functions of Quantized Energy Levels in Carbon Nanotubes

Posted by klaurent Delft

Kavli Affiliate: Sander Tans | Summary:Carbon nanotubes provide a unique system to study one-dimensional quantization phenomena. Scanning tunneling microscopy is used to observe the electronic wave functions that correspond to quantized energy levels in short metallic carbon nanotubes. Discrete electron waves are apparent from periodic oscillations in the differential conductance as a function of the […]

Heavy Quark Production and Decay: t, b, and onia

Posted by klaurent Stanford

Kavli Affiliate: Richard Partridge | Summary:This paper summarizes a variety of recent results on heavy quark production and decay. Considerable progress has been made by CDF and D0 in measuring top quark production and decay properties. The top quark mass been measured with an uncertainty that is less than 3%, a relative precision that is […]

McKay correspondence and Hilbert schemes in dimension three

Posted by klaurent Tokyo

Kavli Affiliate: Yukari Ito | Summary:Let $G$ be a nontrivial finite subgroup of $SL_n(C)$. Suppose that the quotient singularity $C^n/G$ has a crepant resolution $Ď€colon Xto C^n/G$ (i.e. $K_X = shfO_X$). There is a slightly imprecise conjecture, called the McKay correspondence, stating that there is a relation between the Grothendieck group (or (co)homology group) of […]
