Recently,the LHCb experimental group found an exotic state T_(cc)^(+) from the pp→D^(0)D^(0)π^(+)+X process.A key question is whether it is just a molecule or may have a confined tetraquark ingredient.To investigate...

Limits on contact interactions If quarks and leptons are made of constituents, then at the scale of constituent binding energies there should appear new interactions among them. At energies much below the compositenes...

We revisit the compositeness theorem proposed by Weinberg in an effective field theory (EFT) and explore criteria which are sensitive to the structure of S-wave threshold states. On a general basis, we show that the...
Magnetic Monopole SearchesIsolated supermassive monopole candidate events have not been confirmed. The most sensitive experiments obtain negative results.
The latest unpublished results are described in the "Quark and Lep- ton Compositeness" review.SEARCHES FOR QUARK AND LEPTON COMPOSITENESSRevised 2001 by K. Hagiwara (KEK), and K. Hikasa and M. Tanabashi (Tohoku U...

The transverse charge density of pions is calculated based on relativistic quantum mechanics, where the pion is regarded as a quark-antiquark bound state. Corrections from the two spin-1/2 constituents and from the wa...
