Abstract:

In this study, we investigate the sensitivity of the Cherenkov Telescope Array (CTA) and Fermi Large Area Telescope (Fermi-LAT) to dark matter (DM) annihilation in γ-ray lines. We focus on observations of the Galactic Center (GC), dwarf Spheroidal galaxies (dSphs), and galaxy clusters (GCls). Specifically, we compare the reach of the GC with that of dSphs, considering the poorly known putative core radius of the DM distribution. Surprisingly, we find that the currently best dSph candidates present a more promising target than the GC, especially for core radii ranging from one to a few kiloparsecs.
In addition to CTA prospects, we extend our analysis to incorporate Fermi-LAT data. Recent advancements in computations have highlighted the impact of Sommerfeld enhancement and bound-state formation on the annihilation cross section of Minimal Dark Matter (MDM) multiplets. Exploring this new paradigm, we examine Fermi-LAT data to assess its capability to detect or rule out a potential line arising from bound-state formation processes. Our findings reveal that the Fermi-LAT data effectively rules out the MDM 5plet at a significance level of 2σ, demonstrating the importance of considering enhanced cross sections and new annihilation signatures in the quest to unravel the mysteries of dark matter.

I briefly describe the physical considerations that lead to nonlocality. The status of nonlocal special relativity is mentioned and recent work in connection with nonlocal gravity is reviewed.

There are different types of approaches to solve P vs NP, some of them are logical approaches. The lecturer's PhD thesis [11] is based on one of these logical approaches 2002 [2], [6]. Till 2011, he and some other logicians made an unsuccessful aƩempt to shed light on this problem in this way. In 2010‐2011, he started to introduce another logical approach based on paradoxes, more specifically ?Unexpected Hanging Paradox?. The goal is to use paradoxes similar to applying paradoxes (Liar Paradoxes) in the Godel?s Incompleteness Theorem [14], [15], [16]. In [5], [16] (2017), he showed by defining a new version of this paradox, we face a contradiction, not a paradox. To cope with this situation, in 2019 Fuzzy Time [4], [17] (or as some of the speaker?s colleagues used it later on, Temporal Continuum (2023) or Continuity in Time (2024)) came into the centre of the subject and discussion. Nevertheless, we have concepts similar to the fuzziness of Time and space in the history of science, Mathematics, Philosophy and Physics [7], [12], [13]. Based on that, the speaker claimed a new interpretation of Quantum Mechanics, the ?Fuzzy time‐particle? interpretation of Quantum Mechanics [1], [3], [4]. ?Theory of Fuzzy Time Computation?, is introduced in [8], [9], [10], monthly seminars of the Iranian Association of Logic [18], and The 10th annual conference of the Iranian Association for Logic (IAL) (2023) [19]. In 2023, this Theory was introduced in a paper in HAL [9] and now it is in development. In this lecture, after defining this Theory, we explain a part of it in details, and as the main conclusion, we prove TC+CON(TC^* )ͰP≠NP.
