ALICE takes the next step in understanding the interaction between hadrons（图）
ALICE 强子 相互作用
2023/5/29
In an article recently published in Physical Review Letters, the ALICE collaboration has used a method known as femtoscopy to study the residual interaction between two-quark and three-quark particles...
The Large Hadron Collider beauty (LHCb) collaboration today announced results that confirm the existence of exotic hadrons – a type of matter that cannot be classified within the traditional quark mod...
Pseudorapidity distributions of produced charged hadrons in pp collisions at RHIC and LHC energies
produced charged hadrons RHIC LHC energies
2011/7/21
The energy dependence of charged-hadron production in proton-proton collisions at RHIC and LHC energies is investigated in a nonequilibrium-statistical relativistic diffusion model (RDM) with three so...
Abstract: Assume that hadrons are formed from the emergence string. Usual string should possess two moving states: oscillation and rotation, so we propose corresponding potential and the equation of t...

Propagation the atmosphere ultrahigh-energy charmed hadrons
2011/1/13
Charmed mesons may be produced when a primary cosmic ray or the leading hadron in an air shower collide with an atmospheric nucleon. At energies \ge 10^8 GeV their decay length becomes larger than 10 ...
Azimuthal correlations of electrons from heavy-flavor decay with hadrons in p+p and Au+Au collisions at sqrt(s_NN)=200 GeV
Azimuthal correlations electrons heavy-flavor decay with hadrons p+p and Au+Au collisions sqrt(s_NN)=200 GeV
2011/1/4
Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary scaled p+p collisions. These mea...
Identifying hadronic molecular states and/or hadrons with multi-quark components either with
or without exotic quantum numbers is a long standing challenge in hadronic physics. We suggest
that study...

Experimental data from the PEP-II B-factory at 10.6 GeV center-of-mass (c.m.) energy, obtained via initial-state radiation (ISR) with the BABAR detector, are presented. The cross sections for many had...
Azimuthal asymmetries in production of charged hadrons by high energy muons on polarized deuterium targets
Azimuthal asymmetries polarized deuterium targets high energy muons
2010/3/15
Search for azimuthal asymmetries in semi-inclusive production of charged hadrons by 160 GeV muons on the longitudinally polarized deuterium target, has been performed using the 2002- 2004 COMPASS data...
We search for new charmless decays of neutral $b$--hadrons to pairs of charged hadrons with the upgraded Collider Detector at the Fermilab Tevatron. Using a data sample corresponding to 1 fb$^{-1}$ of...
Transverse momentum and pseudorapidity distributions of charged hadrons in pp collisions at sqrt(s) = 0.9 and 2.36 TeV
Transverse momentum hadrons pp collisions
2010/3/15
Measurements of inclusive charged-hadron transverse-momentum and pseudorapidity distributions are presented for proton-proton collisions at sqrt(s) = 0.9 and 2.36 TeV. The data were collected with the...

relativistic high energy nucleus-nucleus collisions nuclear modification factor transverse collective flow quark combination model
2009/8/17
The centrality dependence of transverse momentum spectra for identified hadrons at midrapidity in Au+Au collisions at √sNN= 200GeV is systematically studied in a quark combination model. The pT spectr...

2010/10/19
We discuss finite-size effects on homogeneous nucleation in first-order phase transitions. We study their implications for cosmological phase transitions and to the hadronization of a quark-gluon plas...
