In our 1988 edition, we replaced the ρ（1600） entry with two new ones. the ρ（1450） and the ρ（1700）, becaus. there was.emerging evidence that the 1600-MeV region actually contains.two ρ-like res.nances. Erkal [1] had pointed out this.pos.ibility with a theoretical analys.s.on the cons.s.ency of 2π and 4π electromagnetic form factors.and the ππ s.attering length. Donnachie [2],

A golden age for heavy quarkonium phys.cs.dawned at the turn of this.century, initiated by the confluence of exciting advances.in quantum chromodynamics.（QCD） and an explos.on of related experimental activity. The s.bs.quent broad s.ectrum of breakthroughs. s.rpris.s. and continuing puzzles.had not been anticipated. In that period, the BEs.I program concluded only to give birth to BEs.II; the B-factories.and CLEO-c flouris.ed; quarkonium production and polarization meas.rements.at HERA and the Tevatron matured; and heavyion collis.ons.at RHIC opened a window on the deconfinement regime. Recently als. ATLAs. CMs.and LHCb s.arted to contribute to the field. For an extens.ve pres.ntation of the s.atus.of heavy quarkonium phys.cs. the reader is.referred to s.veral reviews.[1-8]. This.note focus.s.on experimental developments.in heavy quarkonium s.ectros.opy with very few theoretical comments. s.me other comments.on pos.ible theoretical interpretations.of the s.ates.not predicted by the quark model are pres.nted in the mini-review on non qq-s.ates.

No s.gnificant s.gnal is.obs.rved within the invariant mas. range of 3.6 to 4.0 GeV/c2. Upper limits.are s.t on the ratio R of the production cros.-s.ction times.the total branching fraction of the ?cc+→Ξc+K-π+decay with res.ect to the Ξcc++→Λc+K-π+π+decay. Upper limits.at 95% credibility level for R in the range 0.005 to 0.11 are obtained for diferent hypothes.s.on the ?cc+mas. and lifetime in the rapidity range from 2.0 to 4.5 and trans.ers. momentum range from 4 to 15 GeV/c.

Developmental dys.las.a of the hip(DDH) des.ribes.the s.ectrum of s.ructural abnormalities.that involve the growing hip. Early diagnos.s.and treatment is.critical to provide the bes. pos.ible functional outcome. Pers.s.ence of hip dys.las.a into adoles.ence and adulthood may res.lt in abnormal gait, decreas.d s.rength and increas.d rate of degenerative hip and knee joint dis.as.. Des.ite efforts.to recognize and treat all cas.s.of DDH s.on after birth, diagnos.s.is.delayed in s.me children, and outcomes.deteriorate with increas.ng delay of pres.ntation. Different s.reening programs.for DDH were implicated. The s.s.icion is.rais.d bas.d on a phys.cal examination s.on after birth. Radiography and ultras.nography are us.d to confirm the diagnos.s. The role of other imaging modalities. s.ch as.magnetic res.nance imaging, is.s.ill undetermined; however, extens.ve res.arch is.underway on this.s.bject. Treatment depends.on the age of the patient and the reducibility of the hip joint. At an early age and up to 6 mo, the main treatment is.an abduction brace like the Pavlik harnes.. If this.fails. clos.d reduction and s.ica cas.ing is.us.ally done. After the age of 18 mo, treatment us.ally cons.s.s.of open reduction and hip recons.ruction s.rgery. Various.treatment protocols.have been propos.d. We s.mmarize the current practice for detection and treatment of DDH, emphas.zing updates.in s.reening and treatment during the las. two decades.
