Both the real and imaginary part of the potential has been modified through the dielectric function by including the anisotropic parameter \u0000 \u0000 ξ\u0000 \u0000 . 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 \u0000 \u0000 Q\u0000 \u0000 Q\u0000 ¯\u0000 \u0000 \u0000 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 \u0000 \u0000 1\u0000 S\u0000 \u0000 states has been studied at constant magnetic field \u0000 \u0000 e\u0000 B\u0000 =\u0000 0.3\u0000  \u0000 G\u0000 e\u0000 \u0000 \u0000 V\u0000 \u0000 \u0000 2\u0000 \u0000 \u0000 \u0000 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.","PeriodicalId":7498,"journal":{"name":"Advances in High Energy Physics","volume":"1 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41345507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The kinematics of decays can be deducted by a twofold ambiguity with a quadratic equation. To resolve the twofold ambiguity, a novel method based on machine learning (ML) is proposed. We study the effect of different sets of features and regressors on the improvement of reconstructed invariant mass squared of \u0000 \u0000 ℓ\u0000 ν\u0000 \u0000 system (\u0000 \u0000 \u0000 \u0000 q\u0000 \u0000 \u0000 2\u0000 \u0000 \u0000 \u0000 ).

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 \u0000 \u0000 c\u0000 \u0000 (the speed of light in a vacuum), \u0000 \u0000 G\u0000 \u0000 (the gravitational constant), and \u0000 \u0000 ħ\u0000 \u0000 (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 \u0000 \u0000 c\u0000 −\u0000 G\u0000 −\u0000 e\u0000 \u0000 or \u0000 \u0000 c\u0000 −\u0000 G\u0000 −\u0000 ħ\u0000 \u0000 and \u0000 \u0000 α\u0000 \u0000 (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.","PeriodicalId":7498,"journal":{"name":"Advances in High Energy Physics","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49604169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
