Sending data for proton collisions at a record-breaking energy level now begins. Data transmission at a record-breaking energy of 13.6 TeV is currently being prepared by the Large Hadron Collider. Scientists from the University of Liverpool are involved in the work as part of global partnerships to collect and evaluate data.

The third data collection run (Run3) for the accelerator began at CERN, located near Geneva on the Swiss-French border.

After more than three years of retrofit and maintenance work to make it even stronger, the beam had begun to re-circulate in circular orbit in April.

Previously, the LHC machine and its injectors were reactivated to operate with new, more intense beams and more energy.

According to the beam operators, the beam is now stable and ready to begin collecting data for scientific purposes.

The LHC (TeV) will now operate continuously for almost 13.6 years at a record speed of 4 trillion electronvolts.

To expand the data samples and generate more collision energy, researchers at the University of Liverpool have joined a worldwide effort to improve the performance of three of the four key LHC experiments(  LHCb, ATLAS ve ALICE ).

Professor Monica D'Onofrio from the University of Liverpool said in her statements.

Now we are ready to collect higher quality, visibly larger data samples than previous studies, he says, “This is a very exciting moment for all of us.

After years spent upgrading the ATLAS detector system with new components, improved data reading and improved online selection will provide new insights.

“We will be able to probe the nature of the Higgs boson with unprecedented accuracy, test whether it decays into new particles such as those that might form dark matter, and search for new physics at the highest energy achieved by an accelerator,” he says.

Since the beginning of LHC operations, our group in Liverpool has been at the forefront of many of these research and precision measurements, and we look forward to embarking on this new chapter of the ATLAS experiment.

It's also great that in addition to the four main LHC experiments, a whole new set of small experiments set up and built during the extended shutdown will have initial results as Study 3 begins.

created to search for decays of putative new particles with long lifetimes created in LHC collisions and potential dark matter candidates. PHASESIt will be his job.

It will be the task of ATLAS to explore uncharted territory. Undoubtedly exciting times await us and we are all working hard to maximize the potential of these amazing detectors and accelerators.

“After nearly a decade of research and development, the ALICE experiment has completed major updates to the detector, electronics, triggering and computing systems during the LHC's second prolonged shutdown and is ready for the start of today's third operation,” says Professor Marielle.

Chartier is team leader of the University of Liverpool ALICE experiment. ALICE will be able to collect data much faster than the LHC proton-proton, proton-ion and heavy ion collisions in the next decade.

Chartier's statements are as follows;

“I look forward to learning more about the quark-gluon plasma and how well the new Silicon Internal Monitoring System will work to enable high-precision measurements of short-range dynamics in high-temperature quantum chromodynamics.”

The most pixelated and thinnest silicon particle tracker in the LHC, this new detector is the largest silicon pixel tracker ever made and the first to be made entirely of CMOS sensors.

This enormous digital camera with approximately 13 billion pixels and a shutter speed of 50.000 images per second was built, assembled and commissioned by the University of Liverpool in collaboration with STFC Daresbury Laboratory.

Tara Shears, professor of particle physics at Liverpool and working on the LHCb experiment, said: “There is so much we need to understand about the universe: why do matter and antimatter differ; what makes up dark matter; The new physics is revealing itself, we believe is out there somewhere.

This is why the Run 3 run is so important to us.

It will provide us with so much information that it gives us the chance to do extensive research on each of these topics.

In preparation for the start of data collection, the experience LHCb has undergone extensive refurbishment and refinement and we have installed one of the key particle detectors for this in Liverpool. No one expected a pandemic when we planned this!

Despite all the difficulties, this complex detector for Run3 was built, delivered and deployed on time.

This is a testament to the dedication and talent of our amazing team at Liverpool. Thanks to the data from this new detector, the entire LHCb physics program will be possible.
The data reading and selection systems for the four major LHC experiments have undergone significant changes, including new detector systems and computational infrastructure.

Thanks to the adjustments, they will be able to collect significantly more data samples and the data will be of higher quality than previous studies. It is estimated that more collisions will be recorded by the ATLAS and CMS detectors in the Run3 study than by the two physics studies combined.

The LHCb experiment has been completely revamped and hopes to increase the data acquisition rate by a factor of 10, while ALICE hopes to capture a staggering fifty times more collision.

Run 3 will further expand the already highly diversified LHC physics program with expanded data samples and higher collision energy.
