Chapter 270

At 4:00 PM, the sun was still scorching. There weren't many people on the road, and Song Yao and Ding Jiahui ducked into the shopping mall next to the milk tea shop.

"Resurrected on the spot."

Enjoying the cooling air hitting her face, Ding Jiahui let out a long breath and asked curiously, "Is Xu Qingzhou that busy over there?"

"Yeah, he said the Xia Nation team and the American team are competing for the right to speak on the experiment, and the whole group is working day and night on calculations."

At this, Ding Jiahui felt even more dazed. "Sigh~ I'm still feeling smug about getting a scholarship, while my friend is already bringing glory to the country."

Song Yao was already used to Xu Qingzhou's freakishness.

Yeah, freakish—whether it was in academics or daily life. Thinking of this, she couldn't help but glance at her own feet again.

Wang Qiming sneered inwardly.

Read! {

Song Yao stopped in her tracks and raised an eyebrow at her; this seemed to be common knowledge.

She missed that tingling, numbing feeling a little; he still had a month before he returned.

He wasn't skilled in particle physics, but he was proficient in quantum mechanics.

Academician Yang flipped to page 45, pondered for a moment, nodded, and said in a deep voice, "This plan is feasible; leave it to Professor Wang."

Not bad, it should be feasible.

"Two more years."

"Everyone seems to have changed this summer vacation. Look at the first summer vacation, and during the winter vacation, there were parties everywhere—middle school classmates one moment, high school classmates the next. How lively it was."

The wave-particle duality theory in quantum mechanics points out that particles possess both wave-like and particle-like properties. In the study of the Higgs boson's diphoton channel, this dual nature of particles is fully embodied.

"Alright, doesn't seem like anything new. Still, it's quite happy to see the couple I ship actually get together."

20 minutes passed, Cao Weijie finished speaking, and it was the next person's turn.

"I carefully went over the plan last night. I believe that besides the existing method on page 18, we can add a matrix transformation to correct the detector's non-linear response or spatial resolution issues."

However, before he could speak, Wang Qiming had already started: "Little Xu, it's your turn to speak."

Say what you will, Wang Qiming did have some ability.

After Academician Yang sat down, he said directly, "Everyone has finished reading the draft, right? Time is tight. Let's first provide supplementary explanations for the content of the draft. Professor Cao, you start first."

Ding Jiahui seemed to have turned back into the chatterbox from high school, rambling on and on.

Academician Yang's gaze turned to Xu Qingzhou. Seeing him frowning, wondering what he was thinking about, he prepared to interrupt him. Although he felt this young man probably didn't have anything to say, the necessary procedures still had to be followed.

Young man, you need to learn a lesson and be serious during meetings.

"Using optimization algorithms, I'm more inclined toward the gradient descent method to minimize the $\chi^2$ function on page 45 of the plan, thereby finding the optimal parameter values for $\mu, \sigma, a, $ and $\beta$."

Wang Qiming opened his notebook and said slowly.

Ding Jiahui said leisurely, "You and Xu Qingzhou will get married right after graduation."

As he spoke, Cao Weijie walked to the whiteboard on the side and scribbled down formulas and steps.

The 15th passed. At 8:00 AM Swiss time, the Xia Nation team opened their 4th major meeting. After 5 days of hard work, a draft for the analysis of the diphoton channel appeared in everyone's hands.

To overcome this difficulty, could we construct a model containing interference terms and use the superposition principle of quantum mechanics and the probability amplitude addition rule to accurately describe and predict this interference phenomenon?

"Yaoyao, Yaoyao?" "Ah, you really have thought about it."

Soon it was the turn of Wang Qiming, who was sitting opposite Xu Qingzhou.

"Hmm?"

Chen Peipei, the second youngest girl in the Xia Nation team, shook her head: "I have nothing to add."

Xu Qingzhou was still considering the previous problem and already had a train of thought.

"What are you thinking about, so engrossed?"

Zhang Changqing sighed and said, "Unfortunately, what we lack right now is time."

"As for now, the only phone call I've received was a sales call."

The professor surnamed "Gao" shook his head: "I don't have any ideas on my end. This is already the best plan that could be made in a short time."

Song Yao's earlobes were a bit hot. She looked elsewhere and said, "I was thinking about what I wanted to say just now?"

While Wang Qiming was speaking, Xu Qingzhou also found the $\chi^2$ function. This function belongs to the realm of statistics, a form of statistical inference, and is an important tool that can assist in describing the signal shape of Higgs boson decay into diphotons.

However, Chen Peipei secretly glanced at that face opposite her, which was even younger than hers. This junior brother should be about the same age as her? Next, only one professor named Qiu Peng provided additions.

So... "Team Leader Shen." Academician Yang looked at Shen Yuanjie.

In a foreign land, both being Xia Nation people and in the same research group, one couldn't do anything excessive, or the reputation would be ruined, but there was no problem with being linguistically disgusting.

Even her own boss had no ideas; what could she possibly add?

!.

Shen Yuanjie also shook his head. He wasn't very satisfied with the current analysis results either, but there was no better way.

Seeing this, Wang Qiming narrowed his eyes and continued: "Although Little Xu is young, his attainments in mathematics are not low; he can be considered to have broken the age record for participants in the Xia Nation team. Looking at your expression, you must have some good ideas, right? Say it out and let everyone hear."

Reminded by Song Yao, Ding Jiahui also remembered she had something to share and said, "I wanted to say that another earth-shattering piece of gossip has happened in our high school classmate circle."

Xu Qingzhou's gaze darkened slightly, his thoughts drifting. He wasn't dwelling on the issue of the other party's strength, but was considering another matter—how to correct the background issue.

Song Yao wasn't actually interested in these gossips, but seeing Ding Jiahui's mysterious look, she still cooperated and asked, "What gossip?"

From the perspective of quantum mechanics, the interference effect between signal and background is actually a manifestation of quantum interference.

"It used to be just rumors, and didn't you two debunk them at the class reunion? Now many details have been added, like you and Xu Qingzhou having already bought a wedding house in Kyoto and planning to get the marriage certificate as soon as you reach the age."

"Same here. Although this model can avoid background contribution and is better than the German experimental team's from last year, the efficiency isn't high, and it requires multiple iterations. According to the current situation, it will take at least 7 days."

"No problem." Wang Qiming nodded with a smile.

Xu Qingzhou came back to his senses.

Zhang Changqing spoke up for Xu Qingzhou, "Junior brother is probably exhausted. Junior brother deserves the credit for creating the big model in the plan."

Academician Yang frowned but didn't speak, or rather, it was hard to speak, so he could only turn his head to look at Xu Qingzhou.

Whoa, a backhanded compliment.

Xu Qingzhou immediately understood Wang Qiming's intention, shook his head inwardly, and smiled lightly, "I do have some new ideas on my end."

As he spoke, he stood up and wrote a row of formulas on the bottom right corner of the third whiteboard: 【b(x; \beta_i, \lambda_j)=p(x; \beta_i)+e(x; \lambda_j】
