🧬 Тетракварки и пентакварки — экзотические частицы, которые не вписываются в классическую тройку «протон–нейтрон–мезон». В отличие от обычных адронов, они состоят из четырёх и пяти кварков соответственно. Теория предсказывала их давно — но только в экспериментах на Большом адронном коллайдере удалось зафиксировать их существование экспериментально.

📡 Весной 2025 года международная коллаборация LHCb получила за эту работу премию Breakthrough Prize — одну из самых авторитетных в мире. В центре внимания — фундаментальные вопросы:
▪️Почему во Вселенной вещество преобладает над антивеществом?
▪️Какие новые состояния материи вообще возможны?

📍В составе проекта — российские исследователи из НИУ ВШЭ и Школы анализа данных (ШАД) Яндекса. Исследование делали на базе лаборатории LAMBDA при поддержки грантов Yandex Cloud и в итоге одними из первых начали внедрять машинное обучение для анализа событий на коллайдере:
▪️использовали CatBoost
▪️разработали генеративные модели
▪️настроили алгоритмы отбора и реконструкции редких распадов

⚙️ Это усилило точность, ускорило обработку и позволило фиксировать процессы, которые раньше терялись в шуме.

📊 Такие результаты не разрушают Стандартную модель, но заставляют взглянуть на неё под другим углом.

💬 Можно ли построить новую физику, не разрушая старую — а дополняя её изнутри?

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

Q: What is Telegram? What do I do here?

Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.

Q: Who is Telegram for?

Telegram is for everyone who wants fast and reliable messaging and calls. Business users and small teams may like the large groups, usernames, desktop apps and powerful file sharing options. You can appoint admins with advanced tools to help these communities prosper in peace. Public groups can be joined by anyone and are powerful platforms for discussions and collecting feedback.In case you're more into pictures, Telegram has animated gif search, a state of the art photo editor, and an open sticker platform (find some cool stickers here or here). What's more, there is no need to worry about disk space on your device. With Telegram's cloud support and cache management options, Telegram can take up nearly zero space on your phone.

Q: How is Telegram different from WhatsApp?

Unlike WhatsApp, Telegram is a cloud-based messenger with seamless sync. As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.) of up to 2 GB each. And if you don't want to store all that data on your device, you can always keep it in the cloud.Thanks to our multi-data center infrastructure and encryption, Telegram is faster and way more secure. On top of that, Telegram is free and will stay free — no ads, no subscription fees, forever.

Q: Can I make calls via Telegram?

Yes! Voice calls are currently available to users around the world.

Many modern travelers appear to struggle with managing various aspects of their finances simultaneously while abroad, such as banking, budgeting, investing, trading, and saving. It is important to have apps installed on the device that will help you carry out these necessary tasks.
