One of the first physics results that CMS will hopefully obtain will be the analysis of heavy quarkonium productions, including the Υ cross-section measurement. Since the Υ production cross-section from p-p collisions is expected to be relatively lar...

A combined fit is performed to the BABAR and Belle measurements of the e⁺e^－→φπ⁺π^－ and φf₀(980) cross sections for center-of-mass energy between threshold and 3.0 GeV. The resonance parameters of the φ(1680) and Y(2175) are determined. The mass is (16...

The recently observed X(3872) resonance, which is difficult to assign a conventional cc charmonium state in the quark model, may be interpreted as a molecular state. Such a molecular state is a hidden flavor four quark state because of its charmonium...

We have studied the associated production processes of a neutral top-Higgs in the topcolor assisted technicolor model with a pair of heavy quarks in γγ collisions at the International Linear Collider (ILC). We find that the cross section for tth_t in ...

The gl(1|1) supersymmetric vertex model with domain wall boundary conditions (DWBC) on an N×N square lattice is considered. We obtain the reduction formulae for the two-point boundary correlation functions of the model.

Using the method based on Random Matrix Theory (RMT), the results for the nearest-neighbor distributions obtained from the experimental data on ¹²C-C collisions at
4.2 AGeV/c have been discussed and compared with the simulated data on ¹²C-C collisions...

The proton-rich isotope ¹⁴⁶Ho was produced via the fusion-evaporation reaction ⁹²Mo (⁵⁸Ni, 3p1n). The β-delayed proton decay of ¹⁴⁶Ho was studied by proton-γ coincidence measurements using a He-jet tape transport system. The γ-transitions in ¹⁴⁵Tb fo...

Taking the conservation of baryon number into account in a non-uniform flow model, the rapidity distribution of the net protons at the LHC is predicted. The energy dependence of the rapidity distribution, baryon stopping and collective flow from BNL/...

In this paper, considering the quantum effect of electrons in a super-strong magnetic field, the influence of a super-strong magnetic field on the chemical potential of a non-zero temperature electron is analyzed, the rates of β decay under the super...

The potential energy surfaces of even-even ^142—156Ba are investigated in the constrained reflection-asymmetric relativistic mean-field approach with parameter set PK1. It is shown that for the ground states, ¹⁴²Ba is near spherical, ¹⁵⁶Ba well quadru...

The possibility of the experiment for constraining the symmetry energy E_sym(ρ) at supra-densities via π^－/π⁺ probe on the external target experiment of phase I ( ETE(I) ) with part coverage at forward angle at HIRFL-CSR is studied for the first time b...

By employing the Glauber model, we give the centrality dependences of the numbers of participants and binary nucleon-nucleon collisions in nucleus-nucleus collisions. By taking into account the energy loss of the participants in their multiple collis...

In the construction of a large area neutron detector (neutron wall) that is used to detect neutrons at GeV energies, the performances of all the sampling paddle modules prepared for the neutron wall are investigated with a specially designed test ben...

This study uses Daya Bay RPCs operating in streamer mode to investigate gas mixtures of at least 50% argon, at most 6% isobutane, and with small amounts of SF₆. Isobutane is reduced to 2% without degradation of performance, and SF₆ reduces the noise ...

Physical designing of the pre-chopper in CSNS LEBT is carried out, which includes the deflecting voltage, the length and the width of the deflecting plates, and the gap between the deflecting plates. The most outstanding feature of the design is that...

As a promising kind of high current cold cathode, the Ferroelectric Cathode (FEC) has several significant advantages, such as a controllable trigger time, lower vacuum requirement and large emitting area fabricability. The emitting current density of...

In order to realize high energy density physics and plasma physics research at HIRFL-CSR, a magnetic alloy (MA)-loaded cavity has been studied. According to the theoretical calculation and simulation for the MA-loaded cavity, we achieved a better res...

A new SSC (Separated Sector Cyclotron)-Linac is being designed to serve as an injector for
the SSC at the HIRFL (Heavy Ion Research Facility Lanzhou). The beam intensity at the LEBT

In this paper, by using the ``frequency up-conversion'' principle with a high gain harmonic generation free electron laser and an external seed laser, we consider the possibility of modulating a relativistic electron beam on the attosecond scale, so ...

The objective of this study is to investigate a high performance and lower cost compact gamma camera module for a multi-head small animal SPECT system. A compact camera module was developed using a thin Lutetium Oxyorthosilicate (LSO) scintillation c...
