Hunting the Elusive Toponium: A New Approach at the LHC
![The study details distributions of [latex]\mathrm{t\bar{t}}[/latex] events-both those originating from top quark pairs alone and those combined with toponium contributions-across key angular and kinematic observables like [latex]\Delta R[/latex], [latex]\Delta \phi[/latex], [latex]p^{\star}[/latex], [latex]D^{(1)\mathrm{evt}}[/latex], [latex]\cos\theta^{\prime}[/latex], and [latex]\widetilde{M}^{\mathrm{evt}}\_{2}[/latex], normalized to an integrated luminosity of [latex]\mathcal{L}=140[/latex] fb$^{-1}$ at 13 TeV, demonstrating how subtle variations in event characteristics can reshape the apparent signal and potentially obscure the fundamental processes at play.](https://arxiv.org/html/2602.23426v1/2602.23426v1/figures/ttbar_Mtilde2.png)
Researchers are leveraging spin correlations and quantum information tools to sharpen the search for toponium, a fleeting bound state of top and antitop quarks, at the Large Hadron Collider.

It might seem odd to compare the end of the Wild West era to a completely made-up fantasy world, but surprisingly, the two share some common ground. Both experiences center around the journeys of Klyff and Aurthur, with each destination marking a new chapter before they set off on another long adventure.

Dusk Golem shared that Capcom is paying attention to how players and critics are reacting to the Resident Evil 4 remake, and will use that feedback when planning future games in the series. Both Resident Evil 4 and Resident Evil Requiem have received very positive reviews – 94 and 88 on Metacritic, respectively. How well the upcoming Resident Evil – Code: Veronica remake is received will also influence Capcom’s decisions.

On the podcast The Watch, Community writer Andrew Guest revealed they nearly started filming the long-awaited movie continuation after the 2023 Writers Guild of America strike ended. However, a scheduling conflict with one of the actors’ other projects caused further delays. While disappointing, this is actually a positive sign – it confirms the movie is still happening and gives fans hope that it’s moving forward, even if not as quickly as they’d like.

Both stars will remain on the cobbles for at least another year.

This popular live show debuted at the Empress Museum in West London in September 2024 and, due to its success, has been extended to run until September 2026.
Great heavens! The ledger of the blockchain doth reveal a tale most curious. Some $240 million in stablecoins, like so many courtiers at a royal feast, have been deposited, while $67.5 million in Ethereum hath made its exit, stage right. A spectacle most befitting the age of digital folly!

Severino, in a post worthy of a court jester’s monologue, fixates on the one-month chart, where the SuperTrend clings to support like a drunkard to a lamppost. The monthly timeframe, he insists, is a purifying lens, filtering out the cacophony of short-term madness to reveal the “broader cycle” (a phrase as vague as a politician’s promise). At $66,300, Bitcoin teeters above the SuperTrend’s $66,400 threshold, its green hue a sardonic reminder that the macro trend has not yet succumbed to despair. A monthly close below this line, however, would trigger a sell signal-a ritual as inevitable as the sun rising over a doomed kingdom.

Sant’Albano reports that Capcom expressed a desire to return to the roots of the original, horror-focused Resident Evil games. Interestingly, Sant’Albano herself wasn’t very familiar with the Resident Evil series beforehand, so she had to catch up by watching gameplay footage of the older titles.

The new horror action game came out right before the weekend on February 27, 2026, and early sales numbers look very promising.
