پژوهشگران در سرن، دقت اندازه‌گیری جرم کوارک بالا را به طور قابل توجهی افزایش داده‌اند.

در سال ۱۹۹۵، زمانی که دانشمندان کوارک بالا را کشف کردند، جرم این ذره را بین 151 تا 197 GeV/c2 تخمین زدند که آن را به سنگین‌ترین ذره‌ی بنیادیِ شناخته شده، تبدیل کرد. همچنین، از آنجایی‌که این مقدار یک ورودی کلیدی برای محاسبات مدل استاندارد (برای پیش‌بینی پارامترهای مربوط به فرآیندهای نادر) به‌شمار می‌آید، دقت اندازه‌گیری آن حائز اهمیت است.

اکنون کولبریشن‌های CMS و ATLAS در LHC، با جمع‌آوری پانزده اندازه‌گیری مختلف، دقیق‌ترین مقدار جرم کوارک بالا را تا به امروز، این مقدار گزارش کرده‌اند:
172.52 ±0.33 GeV/c2

Title:

What is (conformal) anomaly?

Title in Persian:

نابهنجاری (همدیس) چیست؟

Abstract:

Inspired by the “What is…?” column in the Notices of the AMS, this talk aims to provide an informal, nontechnical exposition of the fundamental ideas behind various characterizations of anomalies. In the first part of the talk, I will offer a brief summary of multiple mathematical approaches to classifying and characterizing anomalies in quantum field theories. The second part will focus on the specific example of conformal anomaly in two dimensions, illustrating the concepts discussed earlier and highlighting connections with 2D induced gravity and AdS3/CFT2 duality whenever possible.

Abstract:
An advanced light source for research would drive growth in the Wider Caribbean region. In addition to analyzing the need for such a facility to meet Latin America's scientific priorities, the challenges to its construction are discussed. These are very similar to those faced by the African Light Source (AfLS): training of users, ensuring sustainable financing, the possibility of international financial support and the role of international organizations. This perspective of South-South cooperation has attracted the attention and support of other similar facilities, such as SESAME and LNLS, which can play an important role in training and, in the case of GCLS, in project design. The development and success of the corresponding actions, aimed at obtaining political support from the governments of the region and international organizations, mainly UNESCO, may be favored by the current political scenarios in both regions.

Does the Sun Have a Dark Disk?

Abstract

The Sun’s oblateness has been measured using optical observations. Its gravitational quadrupole moment has been deduced through helioseismology and measurements of its gravitational effects on Mercury’s orbit. The distribution of mass within Mercury’s orbit would only impact the orbital determination, suggesting that discrepancies among various types of assessments may indicate the possible existence of a non-luminous mass. For the first time, we have developed a method to combine these differing measurements to yield new, highly sensitive constraints on the mass distribution within Mercury’s orbit. In this talk, we will show that the most precise measurements indicate the existence of a non-luminous disk within Mercury’s orbit, with a mass significantly heavier than the modeled mass for the circumsolar dust ring observed by the Solar TErrestrial RElations Observatory (STEREO) mission. This suggests a substantial dark matter contribution. Furthermore, the long-standing inconsistency between the element abundances determined from the spectroscopy of the Sun’s surface, and those inferred from its interior through helioseismology, can be reconciled if the Sun formed within a protoplanetary disk. We will discuss how our findings limit the presence of a dark disk or a spherical halo near the Sun and highlight the potential of future orbital measurements of Mercury and near-Sun asteroids to refine these constraints further.

🔰 مقاله آموزشی «مدل کیهان‌شناسی دوره‌ای همدیس راجر پنروز»

🔸 این نوشتار به معرفی مدل کیهان‌شناسی پنروز می‌پردازد؛ مدلی که ادعا می‌کند در آینده بسیار دور، کیهان از ذرات جرم‌دار خالی می‌شود، و در نتیجه از منظر همدیسی با ابتدای کیهان هم‌ارز است. بنابرین کیهان در آینده، گذشته خود را فراموش و دوره‌هایی طولانی را به صورت متناوب تکرار خواهد کرد. همچنین به مسئله آنتروپی بسیار پایین کیهان اوّلیه و فرضیۀ انحنای ویل نیز پرداخته شده است.
