Chapter 412: Do you want to take some supplements?

The next day, 10:00 AM.

When Song Yao came out after taking a shower, she saw her boyfriend lying on the sofa, staring at the ceiling with lifeless eyes.

Is he that tired...

She walked over and poked Xu Qingzhou's face with her fingertip.

"The floor has been mopped, and the dishes have been dragged, I'm resting for a while."

After finishing breakfast, Xu Qingzhou didn't move, just wanting to lie down and recuperate. He didn't fall asleep until after two last night; staying up late was one thing, but there was also physical labor.

Even an iron body couldn't take it.

This guy seemed to be really tired, starting to talk nonsense.

Letting Xu Qingzhou lie down, she got up and went to the bedroom to clean up the aftermath on the bed.

The torn stockings could be thrown away directly.

Just...

She glanced at the Hanfu she bought last time in the dirty clothes basket. Counting it up, this was the only one that needed washing. Right, there were also the sheets and quilt covers.

Getting more and more perverted.

She refused these strange behaviors, but was pestered by this guy Xu Qingzhou... and even forced.

Well, actually, in secret, she also cooperated a little bit.

Thinking about it this way, the guilt in Song Yao's heart suddenly disappeared.

That's right, that's right, the culprit was still Xu Qingzhou, what did it have to do with her.

Besides clothes, there were also things like the splits...

Pfft~

Big pervert.

Song Yao spat secretly; indeed, one shouldn't make decisions at night, it was too easy to go off track...

However, it really felt different.

"Phew~"

Song Yao felt her face burning hot, spat out a breath, patted her chest, and hurriedly threw away some strange images in her mind.

11:00 AM.

Song Yao hung up the washed sheets and quilt covers. Seeing that the time was about right, she went to the refrigerator to see what ingredients were there, and at the same time asked Xu Qingzhou on the sofa, "What do you want to eat for lunch?"

"Anything is fine."

Xu Qingzhou changed to a comfortable position and lay down. Napping on the sofa for half an hour actually restored his energy.

Song Yao didn't ask him, staring at the refrigerator and thinking about what dishes she could make. In high school, she hated these oils and smokes, but now she enjoyed it.

This is what life is called.

She carried the vegetables and looked back at the boy on the sofa.

Wondering if she should buy something back for him to take supplements.

Weakling.

"Your eyes are a bit strange."

"No... alright, do you want to... take some supplements?"

"No need!"

"But you..."

"I'm fine."

Xu Qingzhou stood up with a dark face, thinking that next time he must let Song Yao try being the one who moves. This girl usually acts domineering, but after a few minutes, she pitifully says she's tired.

Song Yao pursed her lips and took the vegetables into the kitchen. Being able to make the guy who usually causes trouble so miserable was still quite a sense of achievement.

"Hiss~"

On this side, Song Yao entered the kitchen, and Xu Qingzhou grinned, couldn't help but support his waist. It had to be said, he was really tired.

Having been a nanny for the school beauty Song for more than ten days, now that Song Yao was cooking, he had no psychological burden and planned to continue yesterday's calculations.

Xu Qingzhou first used the traditional resonance Λ and Σ to fit the data. Here, it was necessary to consider 14 states. In each of their decays, there were 4 or 6 independent ls, where l is angular momentum and s is the total spin in a8 decay.

Possible amplitudes...

Xu Qingzhou narrowed his eyes.

Not all of these states were produced in the final state, nor could all allowed decay angular momenta (ls coupling) exist.

His train of thought gradually unfolded: "To make the most general description possible, all possible states and decay angular momenta were used first. Then the data was fitted to this model with 146 free ls coupling coefficients, and the mass and width of the resonance states were fixed at their pdg values."

"That's right, very feasible."

Richard had already completed part of the work, which was screening the samples.

In collision events, some information might not be helpful for the search for pentaquark particles, such as particle trajectories or energy deposition unrelated to pentaquark particle decay. This information needed to be removed to reduce the complexity of data analysis.

Now, the wave function model was done.

He planned to make another decay chain model. Pentaquark particles are usually produced through the decay process of certain baryons. Therefore, it was necessary to build a decay chain model to describe how pentaquark particles decay from a baryon into other particles.

Searching through countless abnormal peaks to see if there were any decay patterns similar to the current one.

Everything was going quite smoothly.

The third week.

The personnel for the course selection had been fixed.

Of the previous 22 people, only 12 remained, but 13 new people joined, so the class he was teaching could be considered full.

Sun Simin, Dino Connally, and additionally, Ma Ersi, who was in a dazed state for most of the class.

Xu Qingzhou was quite surprised; he originally thought this guy would quit.

The reason he had a deep impression of Ma Ersi was that this guy's calculation last time was quite interesting; the whole process didn't have too many fancy techniques, and he used simple operations.

However, compared to the second class, the number of auditors in this class decreased by one-third.

This was a normal phenomenon.

Whether abroad or at home, there was no shortage of people looking for novelty and strangeness; it would be fine once the heat passed.

Both of them were very busy, and a month and a half passed just like that.

In the blink of an eye, Xu Qingzhou and Song Yao had been in Boston for almost four months.

Boston is at 42°28' north latitude, this latitude is roughly equivalent to the vicinity of Mohe City in Xia Nation, but the climate is different. It belongs to a maritime continental climate, with temperatures between 4°C and 11°C.

Outside the window, drizzle fell from the gray sky, sprinkling into the modern city. Rainwater dripped down along the balcony. Opening the window, one could smell the cool scent of soil.

Inside the house, the two cats were lying in their nest, looking up at the hazy weather outside the glass. On a rainy day, this little waste was in a drowsy state even during the day.

"After this rain, the breath of winter will be even stronger."

Xu Qingzhou brewed a cup of coffee for himself and stood by the window watching the rain. Opposite was the Charles River, where one could vaguely see tourists walking by the river with umbrellas. In addition, there were people running and exercising in the rain.

Behind him, Song Yao supported her chin with both hands, looking out the window boredly. "I was originally going to go out and exercise."

"You can also exercise at home." Xu Qingzhou took a sip of coffee, looking towards the sofa, implying something.

Song Yao stared at Xu Qingzhou unkindly. "Are you driving?"

"Clearly it's your thinking that has a problem." Xu Qingzhou denied it flatly. Song Yao was wearing a loose round-neck T-shirt and loose pants today. Even with a small movement, the clothes on her chest would tremble, delicate like a new sprout just pulled out.

Song Yao hummed lightly, accustomed to her thick-skinned boyfriend shifting the blame.

Xu Qingzhou had been busy with that particle physics calculation for this period of time and hadn't been out for many days.

He was exactly like an old otaku on the internet who only knew how to hide in the room all day.

Otakus play games to relax, but Xu Qingzhou needed to use his brain, involving complex calculations.

If this continued, she was worried he would die suddenly.

She originally planned to go out for a run today to relax, but who would have thought it would be light rain all day.

It seemed the exercise plan would have to be postponed.
