Higgs boson adalah partikel kecil yg sgt sulit untuk ditemukan. Ia ditemukan dgn percobaan yg dilakukan di #CERN (Conseil Européen pour la Recherche Nucléaire / The European Organization for Nuclear Research) pusat penelitian fisika terbesar di dunia.

Di sana, para ilmuwan menggunakan mesin besar yg disebut Large Hadron Collider (#LHC) untuk menabrakkan partikel2 kecil bersama2 dgn kecepatan sgt tinggi.
Saat mrk bertabrakan, mrk menghasilkan energi yg cukup besar untuk menghasilkan partikel baru, termasuk Higgs Boson.

#HiggsBoson sgt sulit dideteksi, jd para ilmuwan melihat jejak partikel lain yg dihasilkan saat Higgs boson tercipta.
Penemuan Higgs boson penting krn memperkuat teori Model Standar fisika, yg menjelaskan bgmn partikel2 dasar seperti quark dan elektron berinteraksi.

regarding contracts signed with legal firms to represent PCB at legal forums and copies of contracts signed by #PCB with cricket managers. No response was received from @TheRealPCBMedia @TheRealPCB & I lodged an appeal with @PkInfoCom on 27 July 2021.

in response to my letter, PCB quoted “the magic time frame itself shows that the law at hand is being abused for personal and ulterior motives”. I submitted my argument to @PkInfoCom on 27 Aug 2021 that the response of PCB lawyers is evasive and not satisfactory.

In un acceleratore come l’ LHC del #CERN, le particelle da far scontrare vengono inserite in “pacchetti”
Poi, una volta riempito di pacchetti di particelle tutto il “tubo”,si inizia ad accelerarle
Ad ogni giro, i pacchetti di particelle van più veloci,aumentando la loro energia

Protons are at the heart of every atom, but we still don’t fully understand what's in them
You might remember from school that they contain three tiny particles: two up quarks and one down quark
But new research has found they contain a charm quark too

In the 1960s, physicists began smashing protons together to try and find out what was inside
They quickly learnt that, for most of the time, there were three small particles: two up quarks and one down
But there was also data that didn’t quite make sense

In 1980, at an experiment at the European Muon Collaboration at CERN in Switzerland, data hinted that the proton might also contain a charm quark and its antimatter equivalent, an anticharm
But the result was imprecise and inconclusive, so the issue was never fully resolved...

1/ Guida rapida per decodificare le informazioni che vedrete domani durante la diretta delle le prime collisioni protone-protone a 13.6 TeV. L’acceleratore #LHC segue delle fasi, ogni fase è definita da due parametri: ACCELERATOR MODE e BEAM MODE. #LHCRun3 #CERN
2/ L’ACCELERATOR MODE indica lo stato generale della macchina. Per esempio negli ultimi 2 anni è stato SHUTDOWN perché l’acceleratore era in manutenzione. Un'altra modalità è quella di MACHINE DEVELOPMENT usata dagli operatori di LHC per i loro studi di performance.
3/ Domani l’ACCELERATOR MODE sarà PROTON PHYSICS ossia nella modalità di produzione di collisioni stabili protone-protone. I controlli di LHC sono estremamente complessi in queste settimane il lavoro è stato proprio quelli di trovare le importazioni giuste per PROTON PHYSICS!

¡Tenemos #Nobel de Física 2021! Un 50% para Manabe y Hasselmann por su contribución a los modelos que permitieron predecir el calentamiento global. Pero aquí queremos hablar del 50% que se lleva un gran héroe de la Física Teórica moderna: Giorgio #Parisi.

¿Por qué un héroe? Porque hay pocas figuras que hayan tocado tantos campos como ha hecho él, aportando siempre contribuciones fundamentales, o directamente creándolos; y además, divirtiéndose en el proceso, siempre guiado por la curiosidad más pura. Pero vayamos por partes...
Parisi empezó su carrera trabajando en física de partículas. Con 29 años, participó en el primer gran resultado que lleva su nombre: las ecuaciones de Dokshitzer-Gribov-Lipatov-Altarelli-Parisi (DGLAP para los amigos), …

In 2010, just 3 weeks into the first heavy-ion run, ATLAS saw an unexpectedly large imbalance of energy in pairs of particle jets created in lead-nuclei collisions. 🎇
This was the first observation of the "jet quenching" phenomenon at the LHC! cerncourier.com/a/atlas-observ…

Shortly afterwards, ATLAS scientists made the first measurement of top-quark pair production at the LHC.
This incredibly accurate result required just a few months worth of LHC data, demonstrating the extraordinary potential of the accelerator!

Il settore 4-5 di #LHC è il primo settore dell'acceleratore a raggiungere la temperatura di operazione di 1.9 K (−271.3 °C) grazie al raffreddamento con elio superfluido. 👇👇👇
2/ Il Large Hadron Collider (#LHC) è il più grande apparato criogenico al mondo e uno dei luoghi più freddi della Terra. Tutti i magneti di LHC sono in realtà elettromagneti - magneti in cui il campo magnetico è prodotto dal flusso di una corrente elettrica.
3/ I magneti principali di #LHC funzionano a una temperatura di 1,9 K (-271,3 ° C), più fredda dei 2,7 K (-270,5 ° C) dello spazio esterno. Il sistema criogenico di LHC richiede 40000 guarnizioni per tubi a tenuta stagna.
1/ Come altre attività, anche il #CERN torna a operare normalmente. Entro l’anno prossimo gli aggiornamenti degli esperimenti su abbiamo lavorato negli ultimi 3 anni saranno completati. Un test di collisioni ad alta energia è programmato per l’autunno del 2021.
2/ Spero di poter raccontare “in diretta” tutte queste fasi e quindi scrivo questo thread breve per spiegare alcune nozioni di base della fisica degli acceleratori e degli esperimenti sui collider. Ma cosa si intende quindi per “collider” (collisore)?
3/ Un collider è un sistema di magneti e cavità a radiofrequenza in grado di accelerare e mantenere e far scontrare delle particelle cariche su un’orbita circolare per un tempo lungo: svariate ore.
12 years ago today on 10 September 2008, the world's largest particle accelerator, the #LHC, came online! In honour of this anniversary, today I present a thread of:

2) The 86 meter long #Linac4 is the first accelerator in the chain! It takes negative hydrogen ions (a hydrogen atom with an additional electron) from the source and accelerates them up to 160 MeV!
Linac4 will replace the old Linac2 from next year.

3) Just before entering the Proton Synchrotron Booster (PSB), the hydrogen ions are stripped of their two electrons, leaving just protons. Four superimposed synchrotron rings collect the protons and accelerate them to 2 GeV!

1/ Parliamo ancora della sensibilità di #LHC. Abbiamo già visto che l’anello dell’acceleratore si deforma a causa delle forze di marea esercitate sulla crosta terrestre dal sistema luna-sole. Oggi vediamo se e come eventi sismici possono essere in qualche modo “visti” da LHC. 👇
2/ Come per le maree, ogni perturbazione meccanica dell’anello di 27 km sarà più visibile durante le collisioni. Questo perché, essendo la sezione dei fasci inferiore a quella di un capello, l’accuratezza richiesta per andare in collisione è dell’ordine di una parte per miliardo.
3/ Prima di tutto vediamo che tipo di onde sismiche possono interagire con la struttura meccanica di #LHC.
Per semplificare faremo riferimento a parametri medi come la velocità (tra i 4 e i 6 km/secondo) e ai soli tipi di onda P e S (longitudinale o trasversa).

Questa domenica terza ed ultima puntata sulle forze nucleari. Eravamo arrivati a capire che i costituenti dei nuclei atomici (protoni e neutroni) NON sono affatto palline inerti ma oggetti interagenti e complessi composti a loro volta da quark e gluoni COLORATI. 👇👇👇👇
30/ Sappiamo ora che la sarabanda cromo-dinamica di quark e gluoni rende conto del 99% della massa del protone che quindi è energia. Proviamo ad entrare dentro il protone, nel “Paese delle Meraviglie” in cui quark e gluoni vivono come “particelle libere” pur essendo ingabbiati.
31/ Per cercare di “liberare” quark e gluoni solo per un istante infinitesimo tenteremo di ricostruire le condizioni presenti nell’universo 1 milionesimo di secondo dopo il Big Bang e di osservarle con gli “occhi” traccianti dell’esperimento @ALICEexperiment del #CERN.

To increase the number of collisions in the #LHC by a factor of 10, the High-Luminosity LHC project – #HiLumiLHC – will upgrade the quadrupole magnets in interaction points 1 and 5, using a new superconducting technology based on Niobium-tin.
For High-Luminosity, we need to reach magnetic fields of above 10 T. We will use Niobium-tin superconductor, which will allow reaching magnetic fields of about 12 T, but it requires a complex fabrication process. #HiLumiLHC part two: …
The third video of our series on LHC's upgrade to the #HiLumiLHC is about magnet testing.
Once the model magnet is done, it has to be tested on a cryogenic test stand to see the parameters and be sure that everything works as expected.
