School of Physics: HEPCo Weekly Seminar Series Title of talk Shining the Neutrino Flashlight into the Darkest Places تاباندن پرتو نوترینو به تاریک‌ترین (ناشناخته ترین) مکان‌ها Date and time Tuesday, June 3rd, 2025 (13 Khordad), 2:00 pm (Tehran zone) Link https://www.skyroom.online/ch/schoolofphysics/highenergyseminar Abstract The most phenomenologically important properties of neutrinos are the facts that they don't interact with regular matter very much and that they change which charged lepton they like to interact with during propagation. The presence of matter does modify the propagation of neutrinos, somewhat, and I use this fact along with known oscillation parameters to probe environments that cannot be otherwise directly probed. In particular, I will show how low energy atmospheric neutrinos provide information about the Earth's core and that this can be determined by DUNE. I will also use current data from solar neutrino experiments, constrained by reactor neutrino data, to determine the density in the core of the Sun via neutrinos for the first time, as well as future sensitivities.

Physics Colloquium Speaker Robert Brandenberger Affiliation McGill University Title of talk Do we understand early Universe cosmology? عنوان: آیا کیها‌ن‌شناحت جهان اولیه را می‌فهمیم؟ Date and time, 6-7:30pm, Wednesday 21 May 2025 (31 Ordibehesht 1404) Venue: Online Link https://www.skyroom.online/ch/schoolofphysics/colloquium Abstract I will argue that the usual effective field theory techniques break down in the rapdily expanding background of the early universe. The TCC ("Trans-Planckian Censorship Criterion") plays a key role in the argument. I will then discuss an attempt to obtain an emerging metric space-time and early universe cosmology starting from a quantum mechanical matrix model.

School of Particles and Accelerators Journal Club: Experiments & Phenomenology / Hybrid Format Date: Monday, 5 May 2025/ دوشنبه، 15 اردیبهشت 1404 Time: 11:00 AM - 12:00 PM (Tehran time) Speaker: Dr. Meisam Ghasemi Affiliation: School of Particles and Accelerators, IPM Title: Applications of Classical and Quantum Neural Networks in HEP Analyses Title in Persian: کاربردهای شبکه عصبی کلاسیک و کوانتومی در تحلیل های فیزیک انرژی بالا Abstract: This presentation explores the application of classical and quantum machine learning techniques in particle physics, highlighting their role in tasks such as jet classification, Higgs boson and SUSY identification, and fully hadronic event generation. It begins with an overview of the historical development of artificial intelligence and foundational concepts in deep learning, followed by practical implementations of deep neural networks (DNNs) and convolutional neural networks (CNNs) in high-energy physics analyses, including supersymmetry searches and jet substructure studies. The presentation then introduces quantum machine learning (QML), covering models such as quantum support vector machines (QSVMs) and variational quantum classifiers (VQCs), along with their advantages and challenges in Higgs boson identification. Finally, the use of generative AI is presented as a solution for data generation in both Standard Model and beyond Standard Model scenarios, enabling the production of synthetic datasets significantly faster than traditional Monte Carlo simulations involving MadGraph, Pythia, and Geant4.

Institute for Research in Fundamental Sciences (IPM) SoA Weakly Seminar The new DESI cosmology results: What we have (not) learned about dark energy نتایج جدید کیهان‌شناسی DESI: آموخته‌ها و نیاموخته‌هایمان در مورد انرژی تاریک Yashar Akrami Instituto de Física Teórica (IFT) UAM-CSIC, Spain; Case Western Reserve University, USA Abstract: The new Dark Energy Spectroscopic Instrument (DESI) DR2 results have strengthened the possibility that dark energy is dynamical, i.e., it has evolved over the history of the Universe. This has raised the excitement that the first release of the DESI results generated in both cosmology and high-energy physics communities, and if taken at face value, it is the first time that the standard ΛCDM model of cosmology has faced a serious observational challenge. In this talk, I will first provide an overview of dynamical dark energy and why we may need it, and will then delve into the DESI findings, explaining what we have learned about the nature of dark energy and what we have not. I will particularly emphasize a few caveats which should be considered when interpreting the DESI results. سه‌شنبه 09 ﻣﺎه اردی‌بهشت 1404 ﺳﺎﻋﺖ 11:00 Tuesday, April 29th, 2025 – 11:00 Tehran Time Please note the time and the day of the seminar Venue: SoA’s Seminar Room (in person)

School of Particles and Accelerators Wednesday Weekly Seminar – Virtual Format Date: Wednesday, Apr 23, 2025 / چهارشنبه، 3 اردیبهشت 1404 Time: 05:00 PM - 06:00 PM (Tehran time) Speaker: Dr. Naomi Gendler   Affiliation: Physics Department, Harvard University Title: Axions in the Dark Dimension   Title in Persian: اکسیون ها در بعد تاریک Abstract: The dark dimension scenario, which is motivated from Swampland principles and predicts a single micron scale extra dimension, suggests a consistent framework for the dark sector of the universe. We consider the implications of this scenario for the QCD axion. We find that in the scenario in which the axion is localized on the standard model brane (which we argue is natural), a combination of theoretical (being bounded by the 5D Planck mass) and observational constraints forces it to have decay constant in a narrow range f~10^9 −10^10 GeV.   Indico Link: https://indico.hep.ipm.ir/e/n.gendler Link to Join Virtually: https://www.skyroom.online/ch/ipm-particles/weekly-seminar

Speaker Niayesh Afshordi Affiliation Peremeter Institute Title of talk Copenhagen Survey on Black Holes and Fundamental Physics عنوان: نظرسنجی کپنهاگ دربارهٔ سیاه‌چاله‌ها و فیزیک بنیادی Date and time, 6-7:30pm, Wednesday 27 Farvardin 1404 (16 April 2025). Venue: Online Link https://www.skyroom.online/ch/schoolofphysics/colloquium Abstract The purpose of this survey is to take a snapshot of the attitudes of physicists working on some of the most pressing questions in modern physics, which may be useful to sociologists and historians of science. For this study, a total of 85 completed surveys were returned out of 151 registered participants of the ``Black holes Inside and out'' conference, held in Copenhagen in 2024. The survey asked questions about some of the most contentious issues in fundamental physics, including the nature of black holes and dark energy. A number of surprising results were found. For example, some of the leading frameworks, such as the cosmological constant, cosmic inflation, or string theory - while most popular - gain less than the majority of votes from the participants. The only statement that gains majority approval (by 68% of participants) was that the Big Bang meant “the universe evolved from a hot dense state”, not “an absolute beginning time”. These results provide reasons for caution in describing ideas as consensus in the scientific community when a more nuanced view may be justified. چکیده: هدف این نظرسنجی، ارائهٔ تصویری از نگرش‌های فیزیک‌دانانی است که بر روی برخی از مهم‌ترین پرسش‌های فیزیک مدرن کار می‌کنند، که می‌تواند برای جامعه‌شناسان و تاریخ‌نگاران علم مفید باشد. در این مطالعه، از میان ۱۵۱ شرکت‌کنندهٔ ثبت‌نام‌شده در کنفرانس «سیاه‌چاله‌ها از درون و بیرون» که در سال ۲۰۲۴ در کپنهاگ برگزار شد، مجموعاً ۸۵ پرسش‌نامه تکمیل‌شده دریافت شد. این نظرسنجی به موضوعاتی از جمله ماهیت سیاه‌چاله‌ها و انرژی تاریک پرداخت. نتایج شگفت‌انگیزی به دست آمد؛ برای مثال، برخی از چارچوب‌های پیشرو مانند ثابت کیهانی، تورم کیهانی، یا نظریه ریسمان—با وجود محبوبیت—کمتر از نیمی از آراء شرکت‌کنندگان را به خود اختصاص دادند. تنها گزاره‌ای که اکثریت (۶۸٪ از شرکت‌کنندگان) با آن موافقت کردند، این بود که مهبانگ به معنای «تکامل جهان از یک حالت داغ و چگال» است، نه «آغازی مطلق برای زمان». این نتایج نشان می‌دهد که در توصیف ایده‌ها به عنوان اجماع در جامعهٔ علمی، باید با احتیاط برخورد کرد و دیدگاه‌های دقیق‌تری را مد نظر قرار داد.
