Summary
Vector triplets, a prediction of natural new physics, may explain the ATLAS excess. This hypothesis is compatible with current LHC searches, with signals near expected sensitivity.
Area of Science:
- High Energy Physics
- Particle Physics
- Beyond Standard Model Physics
Background:
- Vector triplets are predicted by natural new physics models involving composite sectors.
- These particles are plausible candidates for discovery at the Large Hadron Collider (LHC).
Purpose of the Study:
- To investigate if a vector triplet could explain the excess observed in the ATLAS boson-tagged jets analysis.
- To assess the compatibility of this hypothesis with existing LHC search results.
Main Methods:
- Analysis of the ATLAS boson-tagged jets excess.
- Compatibility assessment with other relevant LHC searches.
Main Results:
- The vector triplet hypothesis is not excluded by current data.
- The predicted signal strength is close to the sensitivity limits of several LHC channels.
- Some channels show upper fluctuations, while others do not, indicating potential compatibility.
Conclusions:
- The vector triplet hypothesis remains a viable explanation for the ATLAS excess.
- Further detailed studies by experimental collaborations are needed to confirm or refute this hypothesis.
- The findings highlight the importance of precise measurements and analysis of potential signal fluctuations.

01:06Scalar and Vector Triple Products
4.7K
Two vectors can be multiplied using a scalar product or a vector product. The resultant of a scalar product is scalar, while with vector products, the resultant is a vector. These rules of the scalar or vector product between two vectors can be applied to multiple vectors to obtain meaningful combinations. The scalar triple product is the dot product of a vector with the cross product of two vectors.

When understanding the effects of multiple forces acting on an object, vector addition is a crucial concept to grasp. This mathematical concept can be used to calculate the net force acting on an object when two or more forces are involved.
To understand the concept of vector addition, consider the scenario of a ship being pulled by two small tugboats. The two forces, F1 and F2, act concurrently on the ship in different directions. The parallelogram law can be used to calculate the net force...

Vector multiplication of two vectors yields a vector product, with the magnitude equal to the product of the individual vectors multiplied by the sine of the angle between both the vectors and the direction perpendicular to both the individual vectors. As there are always two directions perpendicular to a given plane, one on each side, the direction of the vector product is governed by the right-hand thumb rule.

One might wonder how the captain of a large ship can navigate through the ocean with just a turn of the steering wheel. The answer lies in the concept of two parallel forces that are equal in magnitude and opposite sense, creating a couple moment.
A couple moment is a rotational force that tends to rotate the steering wheel. The wheel's rotation can either be in a clockwise or anticlockwise direction. The right-hand rule is a helpful method for determining the direction of a couple moment....

01:20Vector Operations
2.6K
Vectors are physical quantities that have both magnitude and direction. The vector operations include addition, subtraction, and scalar multiplication.
A vector multiplied by a scalar value is called scalar multiplication. The result obtained is a new vector with a different magnitude. If the scalar is positive, the direction of the vector remains the same, but if it is negative, the direction of the vector is reversed. For example, the product of the mass and velocity yields the momentum.

20.5K
It is cumbersome to find the magnitudes of vectors using the parallelogram rule or using the graphical method to perform mathematical operations like addition, subtraction, and multiplication. There are two ways to circumvent this algebraic complexity. One way is to draw the vectors to scale, as in navigation, and read approximate vector lengths and angles (directions) from the graphs. The other way is to use the method of components.
