رصد باحثون في مصادم الهادرونات الكبير التابع لمركز سيرن اضمحلال جسيمات ينحرف عن تنبؤات النموذج القياسي. تأتي هذه النتائج من تجربة LHCb وتظهر تبايناً بنسبة أربعة انحرافات معيارية عن النظرية. وفي حال تأكيدها، قد تشير هذه النتائج إلى وجود جسيمات أو قوى غير مكتشفة.

تأتي هذه البيانات من دراسات حول "اضمحلالات البطريق" النادرة التي تشمل ميزونات B، والتي تتحول إلى كاون وبيون وميونين اثنين. فحص العلماء الزوايا والطاقات ومعدلات الاضمحلال باستخدام سجلات لحوالي 650 مليار عملية اضمحلال لميزونات B تم جمعها بين عامي 2011 و2018. تختلف القياسات عن توقعات النموذج القياسي، مع احتمال واحد فقط من بين 16000 أن يكون التقلب العشوائي هو تفسير هذا التناقض إذا كانت النظرية صحيحة.

Researchers create an ‘atomic movie’ showing how atoms roam before a radiation-driven decay

Scientists at the Fritz Haber Institute of the Max Planck Society and international collaborators say they have reconstructed a real-time “movie” of atoms moving for up to a picosecond before an electron-transfer-mediated decay (ETMD) event, showing that nuclear motion and geometry can strongly influence when the decay occurs and what it produces.

LHCb experiment discovers elusive Xicc+ particle at CERN

Physicists on the LHCb experiment at CERN's Large Hadron Collider have detected the Xicc+ particle, a baryon containing two charm quarks and one down quark. This heavier analogue of the proton resolves a 20-year-old mystery from a previous experiment. The discovery, confirmed at over 7 sigma significance, highlights upgrades to the LHCb detector.

Muon mystery resolved by precise new calculation

19 مايو، 2026 من إعداد الذكاء الاصطناعي

An international team has shown that a long-standing discrepancy in the muon's magnetic behavior stemmed from earlier calculation limits rather than unknown physics. The work supports the Standard Model and removes one major hint of a possible fifth force of nature.

Dampe telescope reveals universal pattern in cosmic rays

Researchers using the DAMPE space telescope have identified a shared spectral softening in cosmic rays across multiple particle types. The pattern appears at a rigidity of about 15 teraelectron-volts for protons through iron nuclei. This finding, published in Nature, offers new insight into how these high-energy particles behave in the galaxy.

Physicists uncover tiny flaw in time from quantum collapse models

3 مايو، 2026 من إعداد الذكاء الاصطناعي

An international team of physicists has found that quantum collapse models, potentially linked to gravity, introduce a minuscule uncertainty in time itself. This sets a fundamental limit on clock precision, though far below current detection levels. The research, published in Physical Review Research, explores ties between quantum mechanics and gravity.

String theory emerges from basic physics assumptions in new study

Physicists have shown that the key signatures of string theory can arise naturally from a handful of simple rules about particle behavior at extreme energies. Researchers from Caltech, New York University, and a Barcelona institute reached this result using a bootstrap approach that starts with minimal assumptions rather than presupposing strings. The work has been accepted for publication in Physical Review Letters.

CERN to test first road transport of antiprotons

21 مارس، 2026 من إعداد الذكاء الاصطناعي

CERN researchers are set to transport around 100 antiprotons by truck around the campus near Geneva, Switzerland, on Tuesday. This marks the first demonstration of a planned antimatter delivery service to labs across Europe. The experiment, known as STEP, aims to enable precision measurements away from the noisy antimatter factory.
