论文摘要
开放式底部梅森（$ b $（$ b^+$，$ b^0 $），$ \ bar {b} $（$ b^ - $，$ \ bar {b^0} $），$ b_s $（$ {$ {b_ {s}}^0 $υ（2s）$，$υ（3s）$，$υ（4s）$和$υ（1D）$）在有限磁场的存在下使用手性有效的Lagrangian方法在有限磁场的情况下在有限磁场的存在下进行了Isospin非对称奇异的HADRONE培养基的研究。对于带电的重子，磁场引入了Landau能量水平的贡献。开放的底部介子的质量通过与重子和标量介子的相互作用进行了修改，后者在磁化培养基中进行了修改。带电的开放式媒介物在存在磁场的情况下，由于Landau量化而具有额外的正质量转移。 UPSILON状态的中等质量移位源于通过Dilaton场（$χ$）的变化（$χ$）和磁化培养基中的Quark质量项的修饰。开放的底部介子和Upsilon状态在磁化培养基中经历了质量下降。这些介子的质量最初随温度的升高而增加，超过温度值，观察到它们的质量会下降。当温度低于90 MEV时，介体的中等质量随磁场的增加而增加。但是，在高温（T $> $ 90 MEV）下，观察到质量会随着磁场的增加而下降。主要内部效应是密度效应，在GSI的未来设施的Fair实验中计划在不对称重型离子碰撞中具有可观察到的效应。
The masses of open bottom mesons ($B$($B^+$,$B^0$), $\bar{B}$($B^-$,$\bar{B^0}$), $B_s$(${B_{s}}^0$, $\bar{{B_s}^0}$)) and upsilon states ($Υ(1S)$, $Υ(2S)$, $Υ(3S)$, $Υ(4S)$, and $Υ(1D)$) are investigated in the isospin asymmetric strange hadronic medium at finite temperature in the presence of strong magnetic fields using a chiral effective Lagrangian approach. For charged baryons, the magnetic field introduces contribution from Landau energy levels. The masses of the open bottom mesons get modified through their interactions with the baryons and the scalar mesons, which undergo modifications in a magnetized medium. The charged open bottom mesons have additional positive mass shifts due to Landau quantization in the presence of the magnetic field. The medium mass shift of the upsilon states originates from the modification of the gluon condensates simulated by the variation of dilaton field ($χ$) and a quark mass term in the magnetized medium. The open bottom mesons and upsilon states experience a mass drop in the magnetized medium. The masses of these mesons initially increase with a rise in temperature, and beyond a high value of temperature, their masses are observed to drop. When the temperature is below 90 MeV, the in-medium masses of the mesons increase with an increase in the magnetic field. However, at high temperatures (T $>$ 90 MeV), the masses are observed to drop with an increase in the magnetic field. The dominant in-medium effects are the density effects, which can have observable effects in asymmetric heavy-ion collisions planned at compressed baryonic matter experiments at FAIR at the future facility of GSI.
