Weakly Interacting Massive Particles (WIMPs), which could explain the nature of dark matter, can be captured by celestial bodies like the Sun or Earth, leading to enhanced self-annihilation into Standard Model particles including neutrinos detectable by neutrino telescopes such as the IceCube Neutrino Observatory. This article presents a search for muon neutrinos from the center of the Earth performed with 10 years of IceCube data using a track-like event selection. We considered a number of WIMP annihilation channels ((chi chi rightarrow tau ^+tau ^-)/(W^+W^-)/(bbar{b})) and masses ranging from 10 GeV to 10 TeV. No significant excess over background due to a dark matter signal was found while the most significant result corresponds to the annihilation channel (chi chi rightarrow bbar{b}) for the mass (m_{chi }=250) GeV with a post-trial significance of (1.06sigma ).

We observed that integrating SH0ES data points leads to a higher estimation of (H_0) than Pantheon+ (without SH0ES). We perform an extensive MCMC analysis for each combination of data sets, providing constraints on the model parameters.

Our primary finding is that the various dataset combinations in the (f(T, {mathcal {T}})) model we examined relate to a range of Hubble constants, which could contribute to reducing the cosmic tension associated with this parameter. Additionally, we investigate the evolution of matter fluctuations by solving the density contrast evolution equation numerically. We calculate numerical solutions for the weighted growth rate (fsigma _8) using these findings. We plotted the cosmological background parameters to check the behavior of the (f(T, {mathcal {T}})) model in late-time.

In the present work, the critical parameters including the orbital half-period (tau ,) the angular Lyapunov exponent (lambda _L,) and the temporal Lyapunov exponent (gamma _L) are employed to characterize black hole phase transitions within both the extended phase space and holographic thermodynamics frameworks. Under certain conditions, we observe multi-valued function behaviors of these parameters as functions of bulk pressure and temperature in the respective approaches. We propose that (tau ,) (lambda _L,) and (gamma _L) can serve as order parameters due to their discontinuous changes at first-order phase transitions. To validate this, we provide detailed analytical calculations demonstrating that these optical critical parameters follow scaling behavior near the critical phase transition point. Notably, the critical exponents for these parameters are found to be 1/2, consistent with those of the van der Waals fluid. Our findings suggest that static and distant observers can study black hole thermodynamics by analyzing the images of regions around the black holes.\u0000</div>","PeriodicalId":788,"journal":{"name":"The European Physical Journal C","volume":"85 5","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1140/epjc/s10052-025-14221-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143902747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first sector is controlled by the sine-Gordon superpotential, while the second field is submitted to the (chi ^4) one. The fields mutually interact via a nontrivial coupling function (f(chi )) that also changes the kinematics of (phi ). We briefly review the implementation of the Bogomol’nyi–Prasad–Sommerfield (BPS) prescription (Prasad and Sommerfield in Phy Rev Lett 35:12 1975, Bogomolny in Sov J Nucl Phys 24:449, 1976). We then solve the resulting BPS equations for two different interactions f. The first one leads to a single kink-kink configuration, while the second one gives rise to a inhomogeneous sine-Gordon kink lattice. We study the linear stability of these new solutions, focusing on their translational modes. We also explore how the strength of the mutual interaction affects the BPS profiles. In particular, we show that a homogeneous lattice with identical kinks is attained in the regime of extremely strong interactions.\u0000</div>","PeriodicalId":788,"journal":{"name":"The European Physical Journal C","volume":"85 5","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1140/epjc/s10052-025-14211-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143900684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
