In this paper, we study the effects of the widths of unstable particles on the one-loop electroweak corrections for the pp ⟶ WW process at the TeV scale within the framework of the complex mass scheme. We also investigate, for this same process, the unitarity of the theory at high energies.

We studied the effect of momentum space anisotropy on heavy quarkonium states using an extended magnetized effective fugacity quasiparticle model (EQPM). Both the real and imaginary part of the potential has been modified through the dielectric function by including the anisotropic parameter ξ . The real part of the medium-modified potential becomes more attractive in the presence of the anisotropy and constant magnetic field. The binding energy of the 1S, 2S, and 1P quarkonium states including anisotropy effects for both the oblate and the isotropic case were studied. We find that the binding energy of Q Q ¯ states becomes stronger in the presence of anisotropy. However, the magnetic field is found to reduce the binding energy. The thermal width of the charmonium and bottomonium 1 S states has been studied at constant magnetic field e B = 0.3 G e V 2 for isotropic and prolate cases. The effect of magnetic field on the mass spectra of the 1P state for the oblate case was also examined. The dissociation temperature for the 1S, 2S, and 1P states of charmonium and bottomonium has been determined to be higher for the oblate case with respect to the isotropic case.
利用扩展磁化有效逸度准粒子模型(EQPM)研究了动量空间各向异性对重夸克态的影响。电势的实部和虚部都通过介电函数进行了修正，其中包括各向异性参数ξ。在各向异性和恒定磁场的作用下，介质修饰电位的实部更具吸引力。研究了椭球和各向同性情况下1S、2S和1P夸克态的结合能，包括各向异性效应。我们发现Q Q¯态的结合能在各向异性的存在下变得更强。然而，发现磁场降低了结合能。研究了在恒磁场e B = 0.3 G e V 2条件下，各向同性和长向态的夏铵态和底铵态的热宽度。本文还研究了磁场对扁圆情况下1P态质谱的影响。与各向同性的情况相比，扁圆的情况下，正铵和底铵的1S、2S和1P态的解离温度要高。

A model of a particle in finite space is developed and the properties that the particle may possess under this model are studied. The possibility that particles attract each other due to their own wave nature is discussed. The assumption that the particles are spatially confined oscillations (SCO) in the medium is used. The relation between the SCO and the refractive index of the medium in the idealized universe is derived. Due to the plane wave constituents of SCOs, the presence of a refractive index field with a nonzero gradient causes the SCO to accelerate. The SCO locally changes the refractive index such that another SCO is accelerated towards it, and vice versa. It is concluded that the particles can attract each other due to their wave nature and an inverse-square-type acceleration emerges. The constant parameter in the inverse-square-type acceleration is used to compare with the gravitational constant G N , and the possibility of non inverse-square-type behavior is preliminary discussed.

The space available to our perception is three-dimensional with full evidence. The development of physics led to the hypothesis of extra dimensions. It is believed that an important role in the unification of physics should play by the Planck units of mass, length and time, built on the universal constants c (the speed of light in a vacuum), G (the gravitational constant), and ħ (the reduced Planck constant). In August 2021, published work in which it is shown that the fundamental role in the unification of physics, in fact, was played by the Stoney units, built on the universal constants c − G − e or c − G − ħ and α (where e is the elementary electric charge, and α is the fine-structure constant). Using this result, the presented work offers a possible solution to the riddle of extra dimensions; it is shown that any additional spatial dimension can be expressed in terms of the fundamental length or the product of the fundamental time and the speed of light in a vacuum.

We propose generalized uncertainty principle (GUP) with an additional term of quadratic momentum motivated by string theory and black hole physics and providing a quantum mechanical framework for the minimal length uncertainty, at the Planck scale. We demonstrate that the GUP parameter, β 0 , could be best constrained by the gravitational wave observations, GW170817 event. To determine the difference between the group velocity of graviton and that of the light, we suggest another proposal based on the modified dispersion relations (MDRs). We conclude that the upper bound of β 0 reads ≃1060. Utilizing features of the UV/IR correspondence and the apparent similarities between GUP (including nongravitating and gravitating impacts on Heisenberg uncertainty principle) and the discrepancy between the theoretical and the observed cosmological constant Λ (obviously manifesting gravitational influences on the vacuum energy density), known as catastrophe of nongravitating vacuum, we suggest a possible solution for this long-standing physical problem, Λ ≃ 1 0 − 47 GeV4/ℏ3c3.
我们提出了广义不确定性原理(GUP)，并在弦理论和黑洞物理的驱动下增加了二次动量项，并为普朗克尺度下的最小长度不确定性提供了量子力学框架。我们证明GUP参数β 0可以最好地由引力波观测GW170817事件约束。为了确定引力子的群速度和光的群速度之间的差异，我们提出了另一种基于修正色散关系(mdr)的方法。我们得出β 0的上限为≃1060。利用紫外/红外光谱的对应特征和GUP的明显相似性(包括非重力和重力对海森堡测不准原理的影响)以及理论和观测到的宇宙常数Λ的差异(重力对真空能量密度的明显影响)，即非重力真空突变，我们提出了一个可能的解决方案Λ: 1 0−47 GeV4/ h 3c3。

Considering the formalism of symplectic quantum mechanics, we investigate a two-dimensional nonrelativistic strong interacting system, describing a bound heavy quark-antiquark state. The potential has a linear component that is analyzed in the context of generalized fractional derivatives. For this purpose, the Schrödinger equation in phase space is solved with the linear potential. The ground state solution is obtained and analyzed through the Wigner function for the meson c c ¯ . One basic and fundamental result is that the fractional quantum phase-space analysis gives rise to the confinement of quarks in the meson, consistent with experimental results.

The Yang-Mills-aether theory is considered. Implications of the non-Abelian aether-like term, which introduces violation of the Lorentz symmetry, are investigated in a thermal quantum field theory. The thermofield dynamics formalism is used to introduce the temperature effects and spatial compactification. As a consequence, corrections due to the non-Abelian aether term are calculated for the non-Abelian Stefan-Boltzmann law and for the non-Abelian Casimir energy and pressure at zero and finite temperature.
